+Subject: [PATCH 253/725] staging: bcm2835-camera: Ensure timestamps never go
+ backwards.
+
+There is an awkward situation with H264 header bytes. Currently
+they are returned with a PTS of 0 because they aren't associated
+with a timestamped frame to encode. These are handled by either
+returning the timestamp of the last buffer to have been received,
+or in the case of the first buffer the timestamp taken at
+start_streaming.
+This results in a race where the current frame may have started
+before we take the start time, which results in the first encoded
+frame having an earlier timestamp than the header bytes.
+
+Ensure that we never return a negative delta to the user by checking
+against the previous timestamp.

+
+Clang warns:
+
+drivers/staging/vc04_services/bcm2835-camera/controls.c:59:18: warning:
+variable 'mains_freq_qmenu' is not needed and will not be emitted
+[-Wunneeded-internal-declaration]
+static const s64 mains_freq_qmenu[] = {
+                 ^
+1 warning generated.
+
+This is because mains_freq_qmenu is currently only used in an ARRAY_SIZE
+macro, which is a compile time evaluation in this case. Avoid this by
+adding mains_freq_qmenu as the imenu member of this structure, which
+matches all other controls that uses the ARRAY_SIZE macro in v4l2_ctrls.
+This turns out to be a no-op because V4L2_CID_MPEG_VIDEO_BITRATE_MODE is
+defined as a MMAL_CONTROL_TYPE_STD_MENU, which does not pass the imenu
+definition along to v4l2_ctrl_new in bm2835_mmal_init_controls.

-Subject: [PATCH 256/703] staging: bcm2835-camera: Ensure timestamps never go
- backwards.
-
-There is an awkward situation with H264 header bytes. Currently
-they are returned with a PTS of 0 because they aren't associated
-with a timestamped frame to encode. These are handled by either
-returning the timestamp of the last buffer to have been received,
-or in the case of the first buffer the timestamp taken at
-start_streaming.
-This results in a race where the current frame may have started
-before we take the start time, which results in the first encoded
-frame having an earlier timestamp than the header bytes.
-
-Ensure that we never return a negative delta to the user by checking
-against the previous timestamp.

+
+Controls of type MMAL_CONTROL_TYPE_STD_MENU call v4l2_ctrl_new_std_menu
+with a max value and a mask. The max value is one of the defined
+values for the control, however in the config array there are several
+entries where raw numbers have been used instead. Replace these
+with the appropriate enum.

+ V4L2_CID_COLORFX_CBCR behaviour
+
+With V4L2_CID_COLORFX_CBCR calling ctrl_set_colfx it was incorrectly
+assigning the colour values to the enable field of dev->colourfx
+instead of the u and v fields.
+
+Correct the assignments.

+ module
+
+In preparation for adding a video codec V4L2 module which also
+wants to use vchiq-mmal functions, split it out into an
+independent module.
+The minimum number of changes have been made to achieve this
+(eg straight moves where possible) so existing checkpatch
+errors will still be present.

-Subject: [PATCH 265/703] staging: bcm2835-camera: Correct
- V4L2_CID_COLORFX_CBCR behaviour
-
-With V4L2_CID_COLORFX_CBCR calling ctrl_set_colfx it was incorrectly
-assigning the colour values to the enable field of dev->colourfx
-instead of the u and v fields.
-
-Correct the assignments.
-
-Reported as a Coverity issue
-Detected by CoverityScan CID#1419711 ("Unused value")
-
-Reported-by: Colin Ian King <colin.king@canonical.com>

-The minimum number of changes have been made to achieve this

+ passing parameters
+
+The callback from vchi_mmal to the client was growing lots of extra
+parameters. Consolidate them into a single struct instead of
+growing the list further.
+The struct is associated with the client buffer, therefore there
+are various changes to setup various containers for the struct,
+and pass the appropriate members.

+From 4b5f21b730dae52710a930a295c405044557e319 Mon Sep 17 00:00:00 2001
+From: Dave Stevenson <dave.stevenson@raspberrypi.org>
+Date: Mon, 24 Sep 2018 18:15:38 +0100
+Subject: [PATCH 269/725] staging: mmal-vchiq: Add support for event callbacks.
+
+(Preparation for the codec driver).
+The codec uses the event mechanism to report things such as
+resolution changes. It is signalled by the cmd field of the buffer
+being non-zero.
+
+Add support for passing this information out to the client.
+
+Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>

-
-The callback from vchi_mmal to the client was growing lots of extra
-parameters. Consolidate them into a single struct instead of
-growing the list further.
-The struct is associated with the client buffer, therefore there

-Subject: [PATCH 272/703] staging: mmal-vchiq: Add support for event callbacks.
-
-(Preparation for the codec driver).
-The codec uses the event mechanism to report things such as
-resolution changes. It is signalled by the cmd field of the buffer
-being non-zero.
-
-Add support for passing this information out to the client.

+
+This new driver allows contiguous memory blocks to be imported

+confirmed it has finished with it.

+videobuf2 only allowed exporting a dmabuf as a file descriptor,

+
+Split the current implementation into two, one step which

++1) Convert to be a platform driver.
++
++Right now when the module probes, it tries to initialize VCHI and
++errors out if it wasn't ready yet.  If bcm2835-v4l2 was built in, then
++VCHI generally isn't ready because it depends on both the firmware and
++mailbox drivers having already loaded.
++
++We should have VCHI create a platform device once it's initialized,
++and have this driver bind to it, so that we automatically load the
++v4l2 module after VCHI loads.
++
++2) Support SELECTION API to define crop region on the image for encode.
++
++Particularly for resolutions that aren't a multiple of the macroblock
++size, the codec will report a resolution that is a multiple of the macroblock
++size (it has to have the memory to decode into), and then a different crop
++region within that buffer.
++The most common example is 1080P, where the buffer will be 1920x1088 with a
++crop region of 1920x1080.
++
++3) Refactor so that the component creation is only on queue_setup, not open.
++
++Fixes v4l2-compliance failure on trying to open 100 instances of the
++device.

-
-videobuf2 only allowed exporting a dmabuf as a file descriptor,
-but there are instances where having the struct dma_buf is
-useful within the kernel.
-
-Split the current implementation into two, one step which
-exports a struct dma_buf, and the second which converts that
-into an fd.

-Subject: [PATCH 279/703] staging: vc04_services: Add a V4L2 M2M codec driver
-
-This adds a V4L2 memory to memory device that wraps the MMAL
-video decode and video_encode components for H264 and MJPEG encode
-and decode, MPEG4, H263, and VP8 decode (and MPEG2 decode
-if the appropriate licence has been purchased).

-+1) Convert to be a platform driver.
-+
-+Right now when the module probes, it tries to initialize VCHI and
-+errors out if it wasn't ready yet.  If bcm2835-v4l2 was built in, then
-+VCHI generally isn't ready because it depends on both the firmware and
-+mailbox drivers having already loaded.
-+
-+We should have VCHI create a platform device once it's initialized,
-+and have this driver bind to it, so that we automatically load the
-+v4l2 module after VCHI loads.
-+
-+2) Support SELECTION API to define crop region on the image for encode.
-+
-+Particularly for resolutions that aren't a multiple of the macroblock
-+size, the codec will report a resolution that is a multiple of the macroblock
-+size (it has to have the memory to decode into), and then a different crop
-+region within that buffer.
-+The most common example is 1080P, where the buffer will be 1920x1088 with a
-+crop region of 1920x1080.
-+
-+3) Refactor so that the component creation is only on queue_setup, not open.
-+
-+Fixes v4l2-compliance failure on trying to open 100 instances of the
-+device.

+
+RGB3/BGR3 end up being 3 bytes per pixel, which meant that
+the alignment code ended up trying to align using bitmasking
+with a mask of 96.
+That doesn't work, so switch to an arithmetic alignment for
+those formats.

+Subject: [PATCH 282/725] media: vb2: Allow reqbufs(0) with "in use" MMAP
+ buffers
+
+Videobuf2 presently does not allow VIDIOC_REQBUFS to destroy outstanding
+buffers if the queue is of type V4L2_MEMORY_MMAP, and if the buffers are
+considered "in use".  This is different behavior than for other memory
+types and prevents us from deallocating buffers in following two cases:
+
+1) There are outstanding mmap()ed views on the buffer. However even if
+   we put the buffer in reqbufs(0), there will be remaining references,
+   due to vma .open/close() adjusting vb2 buffer refcount appropriately.
+   This means that the buffer will be in fact freed only when the last
+   mmap()ed view is unmapped.
+
+2) Buffer has been exported as a DMABUF. Refcount of the vb2 buffer
+   is managed properly by VB2 DMABUF ops, i.e. incremented on DMABUF
+   get and decremented on DMABUF release. This means that the buffer
+   will be alive until all importers release it.
+
+Considering both cases above, there does not seem to be any need to
+prevent reqbufs(0) operation, because buffer lifetime is already
+properly managed by both mmap() and DMABUF code paths. Let's remove it
+and allow userspace freeing the queue (and potentially allocating a new
+one) even though old buffers might be still in processing.

+
+commit 2f7d8dbb11287cbe9da6380ca14ed5d38c9ed91f upstream.
+
+While having SECURITYFS enabled for the tpm subsystem is beneficial in
+most cases, it is not strictly necessary to have it enabled at all.
+Especially on platforms without any boot firmware integration of the TPM
+(e.g. raspberry pi) it does not add any value for the tpm subsystem,
+as there is no eventlog present.
+
+By turning it from 'select' to 'imply' it still gets selected per
+default, but enables users who want to save some kb of ram by turning
+SECURITYFS off.

-Subject: [PATCH 285/703] media: vb2: Allow reqbufs(0) with "in use" MMAP
- buffers
-
-Videobuf2 presently does not allow VIDIOC_REQBUFS to destroy outstanding
-buffers if the queue is of type V4L2_MEMORY_MMAP, and if the buffers are
-considered "in use".  This is different behavior than for other memory
-types and prevents us from deallocating buffers in following two cases:
-
-1) There are outstanding mmap()ed views on the buffer. However even if
-   we put the buffer in reqbufs(0), there will be remaining references,
-   due to vma .open/close() adjusting vb2 buffer refcount appropriately.
-   This means that the buffer will be in fact freed only when the last
-   mmap()ed view is unmapped.
-
-2) Buffer has been exported as a DMABUF. Refcount of the vb2 buffer
-   is managed properly by VB2 DMABUF ops, i.e. incremented on DMABUF
-   get and decremented on DMABUF release. This means that the buffer
-   will be alive until all importers release it.
-
-Considering both cases above, there does not seem to be any need to
-prevent reqbufs(0) operation, because buffer lifetime is already
-properly managed by both mmap() and DMABUF code paths. Let's remove it
-and allow userspace freeing the queue (and potentially allocating a new
-one) even though old buffers might be still in processing.

+
+This reverts commit ab59590ed562b89db51fe46cee5db96b9bc5abd8.
+
+Issues have been observed in LibreElec as this was unconditionally
+loading the audio driver instead of having the DT parameter to
+enable it.
+
+Includes a partial revert of 2147700eb7a1b9e55e0684f0749114ce35d61571
+which fixed up the error handling.

-
-commit 2f7d8dbb11287cbe9da6380ca14ed5d38c9ed91f upstream.
-
-While having SECURITYFS enabled for the tpm subsystem is beneficial in
-most cases, it is not strictly necessary to have it enabled at all.
-Especially on platforms without any boot firmware integration of the TPM
-(e.g. raspberry pi) it does not add any value for the tpm subsystem,
-as there is no eventlog present.
-
-By turning it from 'select' to 'imply' it still gets selected per
-default, but enables users who want to save some kb of ram by turning
-SECURITYFS off.

- device for the audio driver"
-
-This reverts commit ab59590ed562b89db51fe46cee5db96b9bc5abd8.
-
-Issues have been observed in LibreElec as this was unconditionally
-loading the audio driver instead of having the DT parameter to
-enable it.
-
-Includes a partial revert of 2147700eb7a1b9e55e0684f0749114ce35d61571
-which fixed up the error handling.

+ Using Overlays
+ ==============
+ 
+-Overlays are loaded using the "dtoverlay" directive. As an example, consider
+-the popular lirc-rpi module, the Linux Infrared Remote Control driver. In the
+-pre-DT world this would be loaded from /etc/modules, with an explicit
+-"modprobe lirc-rpi" command, or programmatically by lircd. With DT enabled,
+-this becomes a line in config.txt:
+-
+-    dtoverlay=lirc-rpi
+-
+-This causes the file /boot/overlays/lirc-rpi.dtbo to be loaded. By
+-default it will use GPIOs 17 (out) and 18 (in), but this can be modified using
+-DT parameters:
+-
+-    dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=13
+-
+-Parameters always have default values, although in some cases (e.g. "w1-gpio")
+-it is necessary to provided multiple overlays in order to get the desired
+-behaviour. See the list of overlays below for a description of the parameters
++Overlays are loaded using the "dtoverlay" config.txt setting. As an example,
++consider I2C Real Time Clock drivers. In the pre-DT world these would be loaded
++by writing a magic string comprising a device identifier and an I2C address to
++a special file in /sys/class/i2c-adapter, having first loaded the driver for
++the I2C interface and the RTC device - something like this:
++
++    modprobe i2c-bcm2835
++    modprobe rtc-ds1307
++    echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
++
++With DT enabled, this becomes a line in config.txt:
++
++    dtoverlay=i2c-rtc,ds1307
++
++This causes the file /boot/overlays/i2c-rtc.dtbo to be loaded and a "node"
++describing the DS1307 I2C device to be added to the Device Tree for the Pi. By
++default it usees address 0x68, but this can be modified with an additional DT
++parameter:
++
++    dtoverlay=i2c-rtc,ds1307,addr=0x68
++
++Parameters usually have default values, although certain parameters are
++mandatory. See the list of overlays below for a description of the parameters

+ REPEAT_SEQ_HEADER (#2782)
+
+When handling for V4L2_CID_MPEG_VIDEO_REPEAT_SEQ_HEADER was added
+the firmware would reject the setting if H264 hadn't already been
+selected. This was fixed in the firmware at that point, but to
+enable backwards compatibility the returned error was ignored.
+
+That was Dec 2013, so the chances of having a firmware that still
+has that issue is so close to zero that the workaround can be
+removed.

+Subject: [PATCH 291/725] gpio-ir: change default pull configuration to up
+
+IR receivers like the TSOP series from Vishay and compatible ones
+have active-low open collector outputs with an internal pull up of
+about 30k (according to the TSOP datasheets).
+
+Activating a pull-down resistor on the GPIO will make it work against
+the pull-up in the IR receiver and brings the idle input voltage down
+to about 1.9V (measured on a RPi3B+ with a TSOP4438). While that's
+usually enough to make the RPi see a high signal it's certainly not
+optimal and may even fail when using an IR receiver with a weaker pull-up.
+
+Switching the default GPIO pull to "up" results in an input voltage
+level of about 3.3V and ensures that an idle state (high signal) will
+be detected if no IR receiver is attached.
+

- ==============

--Overlays are loaded using the "dtoverlay" directive. As an example, consider
--the popular lirc-rpi module, the Linux Infrared Remote Control driver. In the
--pre-DT world this would be loaded from /etc/modules, with an explicit
--"modprobe lirc-rpi" command, or programmatically by lircd. With DT enabled,
--this becomes a line in config.txt:
--
--    dtoverlay=lirc-rpi
--
--This causes the file /boot/overlays/lirc-rpi.dtbo to be loaded. By
--default it will use GPIOs 17 (out) and 18 (in), but this can be modified using
--DT parameters:
--
--    dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=13
--
--Parameters always have default values, although in some cases (e.g. "w1-gpio")
--it is necessary to provided multiple overlays in order to get the desired
--behaviour. See the list of overlays below for a description of the parameters
-+Overlays are loaded using the "dtoverlay" config.txt setting. As an example,
-+consider I2C Real Time Clock drivers. In the pre-DT world these would be loaded
-+by writing a magic string comprising a device identifier and an I2C address to
-+a special file in /sys/class/i2c-adapter, having first loaded the driver for
-+the I2C interface and the RTC device - something like this:
-+
-+    modprobe i2c-bcm2835
-+    modprobe rtc-ds1307
-+    echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device

-Subject: [PATCH 294/703] gpio-ir: change default pull configuration to up
-
-IR receivers like the TSOP series from Vishay and compatible ones
-have active-low open collector outputs with an internal pull up of
-about 30k (according to the TSOP datasheets).
-
-Activating a pull-down resistor on the GPIO will make it work against
-the pull-up in the IR receiver and brings the idle input voltage down
-to about 1.9V (measured on a RPi3B+ with a TSOP4438). While that's
-usually enough to make the RPi see a high signal it's certainly not
-optimal and may even fail when using an IR receiver with a weaker pull-up.
-
-Switching the default GPIO pull to "up" results in an input voltage
-level of about 3.3V and ensures that an idle state (high signal) will
-be detected if no IR receiver is attached.

+Subject: [PATCH 295/725] sc16is7xx: Fix for "Unexpected interrupt: 8"
+
+The SC16IS752 has an Enhanced Feature Register which is aliased at the

+Register. If an interrupt is raised while the EFR is mapped in then

+a non-threaded interrupt handler).

+The bInterval is set to 4 (i.e. 8 microframes => 1ms) and the only bit
+that the driver pays attention to is "link was reset". If there's a
+flapping status bit in that endpoint data, (such as if PHY negotiation
+needs a few tries to get a stable link) then polling at a slower rate

+Subject: [PATCH 299/725] ASoC: Add support for AudioSense-Pi add-on soundcard
+
+AudioSense-Pi is a RPi HAT based on a TI's TLV320AIC32x4 stereo codec
+
+This hardware provides multiple audio I/O capabilities to the RPi.
+The codec connects to the RPi's SoC through the I2S Bus.
+
+The following devices can be connected through a 3.5mm jack
+	1. Line-In: Plain old audio in from mobile phones, PCs, etc.,
+	2. Mic-In: Connect a microphone
+	3. Line-Out: Connect the output to a speaker
+	4. Headphones: Connect a Headphone w or w/o microphones
+
+Multiple Inputs:
+	It supports the following combinations
+	1. Two stereo Line-Inputs and a microphone
+	2. One stereo Line-Input and two microphones
+	3. Two stereo Line-Inputs, a microphone and
+		one mono line-input (with h/w hack)
+	4. One stereo Line-Input, two microphones and
+		one mono line-input (with h/w hack)
+
+Multiple Outputs:
+	Audio output can be routed to the headphones or
+		speakers (with additional hardware)

- string
-
-The compatible string was set to "fepi,sgtl5000", which worked for some
-reason in 4.14, but does not work in 4.19, presumably due to some
-change in the kernel matching logic. The correct string is
-"fsl,sgtl5000".

-Subject: [PATCH 301/703] lan78xx: Debounce link events to minimize poll storm
-
-The bInterval is set to 4 (i.e. 8 microframes => 1ms) and the only bit
-that the driver pays attention to is "link was reset". If there's a
-flapping status bit in that endpoint data, (such as if PHY negotiation
-needs a few tries to get a stable link) then polling at a slower rate
-would act as a de-bounce.

-Subject: [PATCH 302/703] ASoC: Add support for AudioSense-Pi add-on soundcard
-
-AudioSense-Pi is a RPi HAT based on a TI's TLV320AIC32x4 stereo codec
-
-This hardware provides multiple audio I/O capabilities to the RPi.
-The codec connects to the RPi's SoC through the I2S Bus.
-
-The following devices can be connected through a 3.5mm jack
-	1. Line-In: Plain old audio in from mobile phones, PCs, etc.,
-	2. Mic-In: Connect a microphone
-	3. Line-Out: Connect the output to a speaker
-	4. Headphones: Connect a Headphone w or w/o microphones
-
-Multiple Inputs:
-	It supports the following combinations
-	1. Two stereo Line-Inputs and a microphone
-	2. One stereo Line-Input and two microphones
-	3. Two stereo Line-Inputs, a microphone and
-		one mono line-input (with h/w hack)
-	4. One stereo Line-Input, two microphones and
-		one mono line-input (with h/w hack)
-
-Multiple Outputs:
-	Audio output can be routed to the headphones or
-		speakers (with additional hardware)

+ single-TT hubs
+
+See https://github.com/raspberrypi/linux/issues/2734
+
+The "Hub Port" field in the split transaction packet was always set
+to 1 for single-TT hubs. The majority of single-TT hub products
+apparently ignore this field and broadcast to all downstream enabled
+ports, which masked the issue. A subset of hub devices apparently
+need the port number to be exact or split transactions will fail.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit c289d6625237aa785b484b4e94c23b3b91ea7e60 upstream.
+
+This reverts commit 7e5d1fd75c3dde9fc10c4472b9368089d1b81d00 ("pwm: Set
+class for exported channels in sysfs") as it causes regression with
+multiple pwm chip[1], when exporting a pwm channel (echo X > export):
+
+- ABI (Documentation/ABI/testing/sysfs-class-pwm) states pwmX should be
+  created in /sys/class/pwm/pwmchipN/pwmX
+- Reverted patch causes new entry to be also created directly in
+  /sys/class/pwm/pwmX
+- 1st time, exporting pwmX will create an entry in /sys/class/pwm/pwmX
+- class attributes are added under pwmX folder, such as export, unexport
+  npwm, symlinks. This is wrong as it belongs to pwmchipN. It may cause
+  bad behavior and report wrong values.
+- when another export happens on another pwmchip, it can't be created
+  (e.g. -EEXIST). This is causing the issue with multiple pwmchip.
+
+Example on stm32 (stm32429i-eval) platform:
+$ ls /sys/class/pwm
+pwmchip0 pwmchip4
+
+$ cd /sys/class/pwm/pwmchip0/
+$ echo 0 > export
+$ ls /sys/class/pwm
+pwm0 pwmchip0 pwmchip4
+
+$ cd /sys/class/pwm/pwmchip4/
+$ echo 0 > export
+sysfs: cannot create duplicate filename '/class/pwm/pwm0'
+...Exception stack follows...
+
+This is also seen on other platform [2]

-Subject: [PATCH 307/703] dwc_otg: fix bug with port_addr assignment for
- single-TT hubs
-
-See https://github.com/raspberrypi/linux/issues/2734
-
-The "Hub Port" field in the split transaction packet was always set
-to 1 for single-TT hubs. The majority of single-TT hub products
-apparently ignore this field and broadcast to all downstream enabled
-ports, which masked the issue. A subset of hub devices apparently
-need the port number to be exact or split transactions will fail.

+Subject: [PATCH 308/725] pwm: Send a uevent on the pwmchip device upon channel
+ sysfs (un)export
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 552c02e3e7cfe2744b59de285aaea70021ae95c9 upstream.
+
+This patch sends a uevent (KOBJ_CHANGE) on the pwmchipN device,
+everytime a pwmX channel has been exported/unexported via sysfs. This
+allows udev to implement rules on such events, like:
+
+SUBSYSTEM=="pwm*", PROGRAM="/bin/sh -c '\
+        chown -R root:gpio /sys/class/pwm && chmod -R 770 /sys/class/pwm;\
+        chown -R root:gpio
+/sys/devices/platform/soc/*.pwm/pwm/pwmchip* && chmod -R 770
+/sys/devices/platform/soc/*.pwm/pwm/pwmchip*\
+'"
+
+This is a replacement patch for commit 7e5d1fd75c3d ("pwm: Set class for
+exported channels in sysfs"), see [1].
+
+basic testing:
+$ udevadm monitor --environment &
+$ echo 0 > /sys/class/pwm/pwmchip0/export
+KERNEL[197.321736] change   /devices/.../pwm/pwmchip0 (pwm)
+ACTION=change
+DEVPATH=/devices/.../pwm/pwmchip0
+EXPORT=pwm0
+SEQNUM=2045
+SUBSYSTEM=pwm

+Subject: [PATCH 309/725] usb: dwc2: Disable all EP's on disconnect
+
+commit dccf1bad4be7eaa096c1f3697bd37883f9a08ecb upstream.
+
+Disabling all EP's allow to reset EP's to initial state.
+On disconnect disable all EP's instead of just killing
+all requests. Because of some platform didn't catch
+disconnect event, same stuff added to
+dwc2_hsotg_core_init_disconnected() function when USB
+reset detected on the bus.
+
+Changed from version 1:
+Changed lock acquire flow in dwc2_hsotg_ep_disable()
+function.

-commit c289d6625237aa785b484b4e94c23b3b91ea7e60 upstream.
-
-This reverts commit 7e5d1fd75c3dde9fc10c4472b9368089d1b81d00 ("pwm: Set
-class for exported channels in sysfs") as it causes regression with
-multiple pwm chip[1], when exporting a pwm channel (echo X > export):
-
-- ABI (Documentation/ABI/testing/sysfs-class-pwm) states pwmX should be
-  created in /sys/class/pwm/pwmchipN/pwmX
-- Reverted patch causes new entry to be also created directly in
-  /sys/class/pwm/pwmX
-- 1st time, exporting pwmX will create an entry in /sys/class/pwm/pwmX
-- class attributes are added under pwmX folder, such as export, unexport
-  npwm, symlinks. This is wrong as it belongs to pwmchipN. It may cause
-  bad behavior and report wrong values.
-- when another export happens on another pwmchip, it can't be created
-  (e.g. -EEXIST). This is causing the issue with multiple pwmchip.
-
-Example on stm32 (stm32429i-eval) platform:
-$ ls /sys/class/pwm
-pwmchip0 pwmchip4
-
-$ cd /sys/class/pwm/pwmchip0/
-$ echo 0 > export
-$ ls /sys/class/pwm
-pwm0 pwmchip0 pwmchip4
-
-$ cd /sys/class/pwm/pwmchip4/
-$ echo 0 > export
-sysfs: cannot create duplicate filename '/class/pwm/pwm0'
-...Exception stack follows...
-
-This is also seen on other platform [2]

+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit 4fe4f9fecc36956fd53c8edf96dd0c691ef98ff9 upstream.
+
+Disabling all EP's allow to reset EP's to initial state.
+Introduced new function dwc2_hsotg_ep_disable_lock() which
+before calling dwc2_hsotg_ep_disable() function acquire
+hsotg->lock and release on exiting.
+From dwc2_hsotg_ep_disable() function removed acquiring
+hsotg->lock.
+In dwc2_hsotg_core_init_disconnected() function when USB
+reset interrupt asserted disabling all ep’s by
+dwc2_hsotg_ep_disable() function.
+This updates eliminating sparse imbalance warnings.
+
+Reverted changes in dwc2_hostg_disconnect() function.
+Introduced new function dwc2_hsotg_ep_disable_lock().
+Changed dwc2_hsotg_ep_ops. Now disable point to
+dwc2_hsotg_ep_disable_lock() function.
+In functions dwc2_hsotg_udc_stop() and dwc2_hsotg_suspend()
+dwc2_hsotg_ep_disable() function replaced by
+dwc2_hsotg_ep_disable_lock() function.
+In dwc2_hsotg_ep_disable() function removed acquiring
+of hsotg->lock.

-Subject: [PATCH 311/703] pwm: Send a uevent on the pwmchip device upon channel
- sysfs (un)export
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-commit 552c02e3e7cfe2744b59de285aaea70021ae95c9 upstream.
-
-This patch sends a uevent (KOBJ_CHANGE) on the pwmchipN device,
-everytime a pwmX channel has been exported/unexported via sysfs. This
-allows udev to implement rules on such events, like:
-
-SUBSYSTEM=="pwm*", PROGRAM="/bin/sh -c '\
-        chown -R root:gpio /sys/class/pwm && chmod -R 770 /sys/class/pwm;\
-        chown -R root:gpio
-/sys/devices/platform/soc/*.pwm/pwm/pwmchip* && chmod -R 770
-/sys/devices/platform/soc/*.pwm/pwm/pwmchip*\
-'"
-
-This is a replacement patch for commit 7e5d1fd75c3d ("pwm: Set class for
-exported channels in sysfs"), see [1].
-
-basic testing:
-$ udevadm monitor --environment &
-$ echo 0 > /sys/class/pwm/pwmchip0/export
-KERNEL[197.321736] change   /devices/.../pwm/pwmchip0 (pwm)
-ACTION=change
-DEVPATH=/devices/.../pwm/pwmchip0
-EXPORT=pwm0
-SEQNUM=2045

-Subject: [PATCH 312/703] usb: dwc2: Disable all EP's on disconnect
-
-commit dccf1bad4be7eaa096c1f3697bd37883f9a08ecb upstream.
-
-Disabling all EP's allow to reset EP's to initial state.
-On disconnect disable all EP's instead of just killing
-all requests. Because of some platform didn't catch
-disconnect event, same stuff added to
-dwc2_hsotg_core_init_disconnected() function when USB
-reset detected on the bus.
-
-Changed from version 1:
-Changed lock acquire flow in dwc2_hsotg_ep_disable()
-function.

-Subject: [PATCH 313/703] usb: dwc2: Fix disable all EP's on disconnect
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-commit 4fe4f9fecc36956fd53c8edf96dd0c691ef98ff9 upstream.
-
-Disabling all EP's allow to reset EP's to initial state.
-Introduced new function dwc2_hsotg_ep_disable_lock() which
-before calling dwc2_hsotg_ep_disable() function acquire
-hsotg->lock and release on exiting.
-From dwc2_hsotg_ep_disable() function removed acquiring
-hsotg->lock.
-In dwc2_hsotg_core_init_disconnected() function when USB
-reset interrupt asserted disabling all ep’s by
-dwc2_hsotg_ep_disable() function.
-This updates eliminating sparse imbalance warnings.
-
-Reverted changes in dwc2_hostg_disconnect() function.
-Introduced new function dwc2_hsotg_ep_disable_lock().
-Changed dwc2_hsotg_ep_ops. Now disable point to
-dwc2_hsotg_ep_disable_lock() function.
-In functions dwc2_hsotg_udc_stop() and dwc2_hsotg_suspend()
-dwc2_hsotg_ep_disable() function replaced by
-dwc2_hsotg_ep_disable_lock() function.
-In dwc2_hsotg_ep_disable() function removed acquiring
-of hsotg->lock.

+Subject: [PATCH 316/725] staging: mmal-vchiq: Fix client_component for 64 bit
+ kernel
+
+The MMAL client_component field is used with the event
+mechanism to allow the client to identify the component for
+which the event is generated.
+The field is only 32bits in size, therefore we can't use a
+pointer to the component in a 64 bit kernel.
+
+Component handles are already held in an array per VCHI
+instance, so use the array index as the client_component handle
+to avoid having to create a new IDR for this purpose.

+
+Fixes a v4l2-compliance failure
+v4l2-test-buffers.cpp(415): g_field() == V4L2_FIELD_ANY
+
+The driver only ever produces progresive frames, so field should

+compat_ioctl wasn't defined, so 32bit user/64bit kernel

+VC_MEM_IOC_MEM_PHYS_ADDR was defined with parameter size

-Subject: [PATCH 319/703] staging: mmal-vchiq: Fix client_component for 64 bit
- kernel
-
-The MMAL client_component field is used with the event
-mechanism to allow the client to identify the component for
-which the event is generated.
-The field is only 32bits in size, therefore we can't use a
-pointer to the component in a 64 bit kernel.
-
-Component handles are already held in an array per VCHI
-instance, so use the array index as the client_component handle
-to avoid having to create a new IDR for this purpose.

- queue_setup/CREATE_BUFS
-
-Fixes a v4l2-compliance failure when passed a buffer that is
-too small.
-queue_setup wasn't handling the case where !(*nplanes), as
-used from CREATE_BUFS and requiring the driver to sanity
-check the provided buffer parameters. It was assuming that
-it was always being used in the REQBUFS case where it provides
-the buffer properties.

+Subject: [PATCH 326/725] media: ov5647: Use gpiod_set_value_cansleep
+
+All calls to the gpio library are in contexts that can sleep,
+therefore there is no issue with having those GPIOs controlled
+by controllers which require sleeping (eg I2C GPIO expanders).
+
+Switch to using gpiod_set_value_cansleep instead of gpiod_set_value
+to avoid triggering the warning in gpiolib should the GPIO
+controller need to sleep.

+The driver was powering on the source subdevice as part of STREAMON,

+significant amount of setup required for your device.
+
+Copy the approach taken in the Atmel ISC driver where s_power(1) is called
+on first file handle open, and s_power(0) is called on the last release.

-Subject: [PATCH 329/703] media: ov5647: Use gpiod_set_value_cansleep
-
-All calls to the gpio library are in contexts that can sleep,
-therefore there is no issue with having those GPIOs controlled
-by controllers which require sleeping (eg I2C GPIO expanders).
-
-Switch to using gpiod_set_value_cansleep instead of gpiod_set_value
-to avoid triggering the warning in gpiolib should the GPIO
-controller need to sleep.

-The driver was powering on the source subdevice as part of STREAMON,

+Subject: [PATCH 335/725] bcm2835-dma: Add support for per-channel flags
+
+Add the ability to interpret the high bits of the dreq specifier as
+flags to be included in the DMA_CS register. The motivation for this
+change is the ability to set the DISDEBUG flag for SD card transfers
+to avoid corruption when using the VPU debugger.

+Date: Fri, 21 Dec 2018 12:11:20 +0300
+Subject: [PATCH 338/725] ASoC: pcm512x: Fix a double unlock in
+ pcm512x_digital_mute()
+
+[ Upstream commit 28b698b7342c7d5300cfe217cd77ff7d2a55e03d ]
+
+We accidentally call mutex_unlock(&pcm512x->mutex); twice in a row.
+
+I re-wrote the error handling to use "goto unlock;" instead of returning
+directly.  Hopefully, it makes the code a little simpler.
+
+Fixes: 3500f1c589e9 ("ASoC: pcm512x: Implement the digital_mute interface")

-Subject: [PATCH 338/703] bcm2835-dma: Add support for per-channel flags
-
-Add the ability to interpret the high bits of the dreq specifier as
-flags to be included in the DMA_CS register. The motivation for this
-change is the ability to set the DISDEBUG flag for SD card transfers
-to avoid corruption when using the VPU debugger.

-
-[ Upstream commit 3500f1c589e92e0b6b1f8d31b4084fbde08d49cb ]
-
-Clicks and pops of various volumes can be produced while the device is
-opened, closed, put into and taken out of standby, or reconfigured.
-Fix this, by implementing the digital_mute interface, so that the
-output is muted during such operations.

+Subject: [PATCH 340/725] usb: dwc_otg: Use dma allocation for mphi dummy_send
+ buffer
+
+The FIQ driver used a kzalloc'ed buffer for dummy_send,
+passing a kernel virtual address to the hardware block.
+The buffer is only ever used for a dummy read, so it
+should be harmless, but there is the chance that it will
+cause exceptions.
+
+Use a dma allocation so that we have a genuine bus address,
+and read from that.
+Free the allocation when done for good measure.

- pcm512x_digital_mute()
-
-[ Upstream commit 28b698b7342c7d5300cfe217cd77ff7d2a55e03d ]
-
-We accidentally call mutex_unlock(&pcm512x->mutex); twice in a row.
-
-I re-wrote the error handling to use "goto unlock;" instead of returning
-directly.  Hopefully, it makes the code a little simpler.

+Subject: [PATCH 343/725] staging: vc-sm-cma: Use a void* pointer as the handle
+ within the kernel
+
+The driver was using an unsigned int as the handle to the outside world,
+and doing a nasty cast to the struct dmabuf when handed it back.
+This breaks badly with a 64 bit kernel where the pointer doesn't fit
+in an unsigned int.
+
+Switch to using a void* within the kernel. Reality is that it is
+a struct dma_buf*, but advertising it as such to other drivers seems
+to encourage the use of it as such, and I'm not sure on the implications
+of that.

-Subject: [PATCH 343/703] usb: dwc_otg: Use dma allocation for mphi dummy_send
- buffer
-
-The FIQ driver used a kzalloc'ed buffer for dummy_send,
-passing a kernel virtual address to the hardware block.
-The buffer is only ever used for a dummy read, so it
-should be harmless, but there is the chance that it will
-cause exceptions.
-
-Use a dma allocation so that we have a genuine bus address,
-and read from that.
-Free the allocation when done for good measure.

-Subject: [PATCH 346/703] staging: vc-sm-cma: Use a void* pointer as the handle
- within the kernel
-
-The driver was using an unsigned int as the handle to the outside world,
-and doing a nasty cast to the struct dmabuf when handed it back.
-This breaks badly with a 64 bit kernel where the pointer doesn't fit
-in an unsigned int.
-
-Switch to using a void* within the kernel. Reality is that it is
-a struct dma_buf*, but advertising it as such to other drivers seems
-to encourage the use of it as such, and I'm not sure on the implications
-of that.

+Subject: [PATCH 356/725] staging: mmal-vchiq: Always return the param size
+ from param_get
+
+mmal-vchiq is a reimplementation of the userland library for MMAL.
+When getting a parameter, the client provides the storage and
+the size of the storage. The VPU then returns the size of the
+parameter that it wished to return, and as much as possible of
+that parameter is returned to the client.
+
+The implementation previously only returned the size provided
+by the VPU should it exceed the buffer size. So for parameters
+such as the supported encodings list the client had no idea
+how much of the provided storage had been populated.

-Subject: [PATCH 358/703] staging: mmal_vchiq: Add in the Bayer encoding
- formats
-
-The list of formats was copied before Bayer support was added.
-The ISP supports Bayer and is being supported by the bcm2835_codec
-driver, so add in the encodings for them.
-
-Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.org>

+Subject: [PATCH 359/725] staging: bcm2835_codec: Add support for the ISP as an
+ M2M device
+
+The MMAL ISP component can also use this same V4L2 wrapper to
+provide a M2M format conversion and resizer.
+Instantiate 3 V4L2 devices now, one for each of decode, encode,
+and isp.
+The ISP currently doesn't expose any controls via V4L2, but this
+can be extended in the future.

- from param_get
-
-mmal-vchiq is a reimplementation of the userland library for MMAL.
-When getting a parameter, the client provides the storage and
-the size of the storage. The VPU then returns the size of the
-parameter that it wished to return, and as much as possible of
-that parameter is returned to the client.
-
-The implementation previously only returned the size provided
-by the VPU should it exceed the buffer size. So for parameters
-such as the supported encodings list the client had no idea
-how much of the provided storage had been populated.

-Subject: [PATCH 360/703] staging: mmal-vchiq: If the VPU returns an error,
- don't negate it
-
-There is an enum for the errors that the VPU can return.
-port_parameter_get was negating that value, but also using -EINVAL
-from the Linux error codes.
-Pass the VPU error code as positive values. Should the function
-need to pass a Linux failure, then return that as negative.

+Subject: [PATCH 361/725] staging: bcm2835_codec: Fix handling of
+ VB2_MEMORY_DMABUF buffers
+
+If the queue is configured as VB2_MEMORY_DMABUF then vb2_core_expbuf
+fails as it ensures the queue is defined as VB2_MEMORY_MMAP.
+
+Correct the handling so that we unmap the buffer from vcsm and the
+VPU on cleanup, and then correctly get the dma buf of the new buffer.

-
-The driver was previously working with hard coded tables of

-The components advertise this information via a MMAL parameter,
-so retrieve the information from there during probe, and store

-Subject: [PATCH 362/703] staging: bcm2835_codec: Add support for the ISP as an
- M2M device
-
-The MMAL ISP component can also use this same V4L2 wrapper to
-provide a M2M format conversion and resizer.
-Instantiate 3 V4L2 devices now, one for each of decode, encode,
-and isp.
-The ISP currently doesn't expose any controls via V4L2, but this
-can be extended in the future.

-Subject: [PATCH 363/703] staging: bcm2835_codec: Add an option for ignoring
- Bayer formats.
-
-This is a workaround for GStreamer currently not identifying Bayer
-as a raw format, therefore any device that supports it does not
-match the criteria for v4l2convert.

-If the queue is configured as VB2_MEMORY_DMABUF then vb2_core_expbuf

+Subject: [PATCH 369/725] video: bcm2708_fb: Try allocating on the ARM and
+ passing to VPU
+
+Currently the VPU allocates the contiguous buffer for the
+framebuffer.
+Try an alternate path first where we use dma_alloc_coherent
+and pass the buffer to the VPU. Should the VPU firmware not
+support that path, then free the buffer and revert to the
+old behaviour of using the VPU allocation.

-Subject: [PATCH 372/703] video: bcm2708_fb: Try allocating on the ARM and
- passing to VPU
-
-Currently the VPU allocates the contiguous buffer for the
-framebuffer.
-Try an alternate path first where we use dma_alloc_coherent
-and pass the buffer to the VPU. Should the VPU firmware not
-support that path, then free the buffer and revert to the
-old behaviour of using the VPU allocation.

+Subject: [PATCH 381/725] bcm2835-sdhost: Allow for sg entries that cross pages
+
+The dma_complete handling code calculates a virtual address for a page
+then adds an offset, but if the offset is more than a page and HIGHMEM
+is in use then the summed address could be in an unmapped (or just
+incorrect) page.
+
+The upstream SDHOST driver allows for this possibility - copy the code
+that does so.

-
-The dma_complete handling code calculates a virtual address for a page
-then adds an offset, but if the offset is more than a page and HIGHMEM
-is in use then the summed address could be in an unmapped (or just
-incorrect) page.
-
-The upstream SDHOST driver allows for this possibility - copy the code
-that does so.

+
+The BCM2835 MMC host driver requests a DMA channel on probe but neglects
+to release the channel in the probe error path and on driver unbind.
+
+I'm seeing this happen on every boot of the Compute Module 3: On first
+driver probe, DMA channel 2 is allocated and then leaked with a "could
+not get clk, deferring probe" message. On second driver probe, channel 4
+is allocated.
+
+Fix it.

+Subject: [PATCH 387/725] bcm2835-mmc: Fix duplicate free_irq() on remove
+
+The BCM2835 MMC host driver requests its interrupt as a device-managed
+resource, so the interrupt is automatically freed after the driver is
+unbound.
+
+However on driver unbind, bcm2835_mmc_remove() frees the interrupt
+explicitly to avoid invocation of the interrupt handler after driver
+structures have been torn down.
+
+The interrupt is thus freed twice, leading to a WARN splat in
+__free_irq().  Fix by not requesting the interrupt as a device-managed
+resource.

-
-The BCM2835 MMC host driver requests a DMA channel on probe but neglects
-to release the channel in the probe error path and on driver unbind.
-
-I'm seeing this happen on every boot of the Compute Module 3: On first
-driver probe, DMA channel 2 is allocated and then leaked with a "could
-not get clk, deferring probe" message. On second driver probe, channel 4
-is allocated.
-
-Fix it.

+The default resolution code was different for each role

+
+commit 16688453661b6d5159be558a1f8c1f54463a420f upstream.
+
+Add a type attribute so userspace is able to know how the data is stored as
+this can help taking the correct decision when selecting which device to
+use. This will also help program display the proper warnings when burning
+fuses for example.

+Subject: [PATCH 396/725] rtc: rv3028: add new driver
+
+upstream commit e6e7376cfd7b3f9b63de3a22792f64d9bfb2ab53.
+
+Add a driver for the MicroCrystal RV-3028. It is a SMT Real-Time Clock
+Module that incorporates an integrated CMOS circuit together with an XTAL.
+It has an i2c interface.
+
+The driver handles date/time, alarms, trickle charging, timestamping,
+frequency offset correction, EEPROM and NVRAM.

++Generic device tree bindings for Real Time Clock devices
++========================================================
++
++This document describes generic bindings which can be used to describe Real Time
++Clock devices in a device tree.
++
++Required properties
++-------------------
++
++- compatible : name of RTC device following generic names recommended practice.
++
++For other required properties e.g. to describe register sets,
++clocks, etc. check the binding documentation of the specific driver.
++
++Optional properties
++-------------------
++
++- start-year : if provided, the default hardware range supported by the RTC is
++               shifted so the first usable year is the specified one.
++
++The following properties may not be supported by all drivers. However, if a
++driver wants to support one of the below features, it should adapt the bindings
++below.
++- trickle-resistor-ohms :   Selected resistor for trickle charger. Should be given
++                            if trickle charger should be enabled
++- trickle-diode-disable :   Do not use internal trickle charger diode Should be
++                            given if internal trickle charger diode should be
++                            disabled
++- wakeup-source :           Enables wake up of host system on alarm
++- quartz-load-femtofarads : The capacitive load of the quartz(x-tal),
++                            expressed in femto Farad (fF).
++                            The default value shall be listed (if optional),
++                            and likewise all valid values.
++
++Trivial RTCs
++------------
++
++This is a list of trivial RTC devices that have simple device tree
++bindings, consisting only of a compatible field, an address and
++possibly an interrupt line.

-Subject: [PATCH 397/703] staging: bcm2835-codec: Refactor default resolution
- code
-
-The default resolution code was different for each role
-as compressed formats need to pass bytesperline as 0 and
-set up customised buffer sizes.
-This is common setup, therefore amend get_sizeimage and
-get_bytesperline to do the correct thing whether compressed
-or uncompressed.

-
-commit 16688453661b6d5159be558a1f8c1f54463a420f upstream.
-
-Add a type attribute so userspace is able to know how the data is stored as
-this can help taking the correct decision when selecting which device to
-use. This will also help program display the proper warnings when burning
-fuses for example.

+ deprecated
+
+commit 04d979d7a7bac2f645cd827ea37e5ffa5b4e1f97 upstream.
+
+SND_SOC_DAPM_MICBIAS is deprecated, replace it with SND_SOC_DAPM_SUPPLY.
+
+MICBIAS voltage wasn't supplied to the microphone with the older
+SND_SOC_DAPM_MICBIAS widget, hence the microphone wouldn't work.
+
+This patch fixes the problem.

-+Generic device tree bindings for Real Time Clock devices
-+========================================================
-+
-+This document describes generic bindings which can be used to describe Real Time
-+Clock devices in a device tree.
-+
-+Required properties
-+-------------------
-+
-+- compatible : name of RTC device following generic names recommended practice.
-+
-+For other required properties e.g. to describe register sets,
-+clocks, etc. check the binding documentation of the specific driver.
-+
-+Optional properties
-+-------------------
-+
-+- start-year : if provided, the default hardware range supported by the RTC is
-+               shifted so the first usable year is the specified one.
-+
-+The following properties may not be supported by all drivers. However, if a
-+driver wants to support one of the below features, it should adapt the bindings
-+below.
-+- trickle-resistor-ohms :   Selected resistor for trickle charger. Should be given
-+                            if trickle charger should be enabled
-+- trickle-diode-disable :   Do not use internal trickle charger diode Should be
-+                            given if internal trickle charger diode should be
-+                            disabled
-+- wakeup-source :           Enables wake up of host system on alarm
-+- quartz-load-femtofarads : The capacitive load of the quartz(x-tal),
-+                            expressed in femto Farad (fF).
-+                            The default value shall be listed (if optional),
-+                            and likewise all valid values.
-+
-+Trivial RTCs
-+------------
-+
-+This is a list of trivial RTC devices that have simple device tree
-+bindings, consisting only of a compatible field, an address and
-+possibly an interrupt line.

+Subject: [PATCH 400/725] ASoC: tlv320aic32x4: Break out clock setting into
+ separate function
+
+commit bf31cbfbe25001036e1e096b1c260bf871766ea5 upstream.
+
+Break the clock setting logic out from the main hw_params.  It's
+rather large and unweildy and makes for a large function.  This
+also better enables some of the following changes to the clock
+tree access in the driver.

+Subject: [PATCH 402/725] ASoC: tlv320aic32x4: Model PLL in CCF
+
+commit 514b044cba667e4b7c383ec79b42b997e624b91d upstream.
+
+Model and manage the on-board PLL as a component in the Core
+Clock Framework.  This should allow us to do some more complex
+clock management and power control.  Also, some of the
+on-board chip clocks can be exposed to the outside, and this
+change will make those clocks easier to consume by other
+parts of the kernel.

-Subject: [PATCH 402/703] ASoC: tlv320aic32x4: SND_SOC_DAPM_MICBIAS is
- deprecated
-
-commit 04d979d7a7bac2f645cd827ea37e5ffa5b4e1f97 upstream.
-
-SND_SOC_DAPM_MICBIAS is deprecated, replace it with SND_SOC_DAPM_SUPPLY.
-
-MICBIAS voltage wasn't supplied to the microphone with the older
-SND_SOC_DAPM_MICBIAS widget, hence the microphone wouldn't work.
-
-This patch fixes the problem.

-
-Break the clock setting logic out from the main hw_params.  It's
-rather large and unweildy and makes for a large function.  This
-also better enables some of the following changes to the clock
-tree access in the driver.

+commit fd2df3aeafa4b4cc468d58e147e0822967034b71 upstream.
+
+Model and manage codec clock input as a component in the Core
+Clock Framework.  This should allow us to do some more complex
+clock management and power control.  Also, some of the
+on-board chip clocks can be exposed to the outside, and this
+change will make those clocks easier to consume by other
+parts of the kernel.

+Subject: [PATCH 404/725] ASoC: tlv320aic32x4: Model DAC/ADC dividers in CCF
+
+commit a51b50062091619915c5155085bbe13a7aca6903 upstream.
+
+Model and manage DAC/ADC dividers as components in the Core
+Clock Framework.  This should allow us to do some more complex
+clock management and power control.  Also, some of the
+on-board chip clocks can be exposed to the outside, and this
+change will make those clocks easier to consume by other
+parts of the kernel.

+Subject: [PATCH 405/725] ASoC: tlv320aic32x4: Model BDIV divider in CCF
+
+commit 9b484124ebd906c4d6bc826cc0d417e80cc1105c upstream.
+
+Model and manage BDIV divider as components in the Core
+Clock Framework.  This should allow us to do some more complex
+clock management and power control.  Also, some of the
+on-board chip clocks can be exposed to the outside, and this
+change will make those clocks easier to consume by other
+parts of the kernel.

-Subject: [PATCH 405/703] ASoC: tlv320aic32x4: Model PLL in CCF
-
-commit 514b044cba667e4b7c383ec79b42b997e624b91d upstream.
-
-Model and manage the on-board PLL as a component in the Core
-Clock Framework.  This should allow us to do some more complex
-clock management and power control.  Also, some of the
-on-board chip clocks can be exposed to the outside, and this
-change will make those clocks easier to consume by other
-parts of the kernel.

+
+commit d25970b5fd51e9fcf0afbe190908ea4049454da4 upstream.
+
+Control the clock gating to the various clock components to use
+the CCF.  This allows us to prepare_enalbe only 3 clocks and the
+relationships assigned to them will cause upstream clockss to
+enable automatically.  Additionally we can do this in a single
+call to the CCF.

-
-Model and manage codec clock input as a component in the Core
-Clock Framework.  This should allow us to do some more complex
-clock management and power control.  Also, some of the
-on-board chip clocks can be exposed to the outside, and this
-change will make those clocks easier to consume by other

+
+commit fbafbf6517274a797e6e6508c18dd8dba5920c89 upstream.
+
+Move these to separate helper functions.  This looks cleaner and fits
+better with the new clock setting in CCF.

+Subject: [PATCH 408/725] ASoC: tlv320aic32x4: Dynamically Determine Clocking
+
+commit 96c3bb00239de4fb5f4ddca42c1f90d6d9b3c697 upstream.
+
+The existing code uses a static lookup table to determine the
+settings of the various clock devices on board the chip.  This is
+limiting in a couple of ways.  First, this doesn't allow for any
+master clock rates other than the three that have been
+precalculated.  Additionally, new sample rates are difficult to
+add to the table.  Witness that the chip is capable of 192000 Hz
+sampling, but it is not provided by this driver.  Last, if the
+driver is clocked by something that isn't a crystal, the
+upstream clock may not be able to achieve exactly the rate
+requested in the driver.  This will mean that clocking will be
+slightly off for the sampling clock or that it won't work at all.
+
+This patch determines the settings for all of the clocks at
+runtime considering the real conditions of the clocks in the
+system.  The rules for the clocks are in TI's SLAA557 application
+guide on pages 37, 51 and 77.

-Subject: [PATCH 408/703] ASoC: tlv320aic32x4: Model BDIV divider in CCF
-
-commit 9b484124ebd906c4d6bc826cc0d417e80cc1105c upstream.
-
-Model and manage BDIV divider as components in the Core
-Clock Framework.  This should allow us to do some more complex
-clock management and power control.  Also, some of the
-on-board chip clocks can be exposed to the outside, and this
-change will make those clocks easier to consume by other
-parts of the kernel.

-
-Control the clock gating to the various clock components to use
-the CCF.  This allows us to prepare_enalbe only 3 clocks and the
-relationships assigned to them will cause upstream clockss to
-enable automatically.  Additionally we can do this in a single

-Subject: [PATCH 411/703] ASoC: tlv320aic32x4: Dynamically Determine Clocking
-
-commit 96c3bb00239de4fb5f4ddca42c1f90d6d9b3c697 upstream.
-
-The existing code uses a static lookup table to determine the
-settings of the various clock devices on board the chip.  This is
-limiting in a couple of ways.  First, this doesn't allow for any
-master clock rates other than the three that have been
-precalculated.  Additionally, new sample rates are difficult to
-add to the table.  Witness that the chip is capable of 192000 Hz
-sampling, but it is not provided by this driver.  Last, if the
-driver is clocked by something that isn't a crystal, the
-upstream clock may not be able to achieve exactly the rate
-requested in the driver.  This will mean that clocking will be
-slightly off for the sampling clock or that it won't work at all.
-
-This patch determines the settings for all of the clocks at
-runtime considering the real conditions of the clocks in the
-system.  The rules for the clocks are in TI's SLAA557 application
-guide on pages 37, 51 and 77.

+
+Some architectures do not yet support the common clock API at all but

+ Mode Voltage
+
+commit 44ceee847e27c828f2f1ef4e400e6bc0c8d04de3 upstream.
+
+Add a switch for setting common mode voltage.  This can allow
+for higher drive levels on the amplifier outputs.

+Subject: [PATCH 417/725] ASoC: tlv320aic32x4: Add Playback PowerTune Controls
+
+commit d3e6e374566e1154820a9a3dc82f7eef646fcf95 upstream.
+
+PowerTune controls the power level of the chip.  On playback this
+indirectly controls things like the gain of the various output
+amplifiers.  This can allow for the decrease of output levels
+from the codec.  This adds controls for those power levels to
+the driver.

+Subject: [PATCH 419/725] dwc_otg: only do_split when we actually need to do a
+ split
+
+The previous test would fail if the root port was in fullspeed mode
+and there was a hub between the FS device and the root port. While
+the transfer worked, the schedule mangling performed for high-speed
+split transfers would break leading to an 8ms polling interval.

-
-commit d3e6e374566e1154820a9a3dc82f7eef646fcf95 upstream.
-
-PowerTune controls the power level of the chip.  On playback this
-indirectly controls things like the gain of the various output
-amplifiers.  This can allow for the decrease of output levels
-from the codec.  This adds controls for those power levels to
-the driver.

+
+Fetching the geometry from the ILI251x registers seems unreliable and

-Subject: [PATCH 422/703] dwc_otg: only do_split when we actually need to do a
- split
-
-The previous test would fail if the root port was in fullspeed mode
-and there was a hub between the FS device and the root port. While
-the transfer worked, the schedule mangling performed for high-speed
-split transfers would break leading to an 8ms polling interval.

-Subject: [PATCH 423/703] Input: ili210x - fetch touchscreen geometry from DT
-
-commit f67cc3e927d8414ad3872e046764534ea1f5db0d upstream
-
-Fetching the geometry from the ILI251x registers seems unreliable and
-sometimes returns all zeroes. Add support for fetching the geometry and
-axis inversion from DT instead.

+ URBs
+
+kill_urbs_in_qh_list() is practically only ever called with the fiq lock
+already held, so don't spinlock twice in the case where we need to cancel
+an isochronous transfer.
+
+Also fix up a case where the global interrupt register could be read with
+the fiq lock not held.
+
+Fixes the deadlock seen in https://github.com/raspberrypi/linux/issues/2907

+Subject: [PATCH 429/725] sound: Fixes for audioinjector-octo under 4.19
+
+1. Move the DT alias declaration to the I2C shim in the cases
+where the shim is enabled. This works around a problem caused by a
+4.19 commit [1] that generates DT/OF uevents for I2C drivers.
+
+2. Fix the diagnostics in an error path of the soundcard driver to
+correctly identify the reason for the failure to load.
+
+3. Move the declaration of the clock node in the overlay outside
+the I2C node to avoid warnings.
+
+4. Sort the overlay nodes so that dependencies are only to earlier
+fragments, in an attempt to get runtime dtoverlay application to
+work (it still doesn't...)
+

-Subject: [PATCH 432/703] sound: Fixes for audioinjector-octo under 4.19
-
-1. Move the DT alias declaration to the I2C shim in the cases
-where the shim is enabled. This works around a problem caused by a
-4.19 commit [1] that generates DT/OF uevents for I2C drivers.
-
-2. Fix the diagnostics in an error path of the soundcard driver to
-correctly identify the reason for the failure to load.
-
-3. Move the declaration of the clock node in the overlay outside
-the I2C node to avoid warnings.
-
-4. Sort the overlay nodes so that dependencies are only to earlier
-fragments, in an attempt to get runtime dtoverlay application to
-work (it still doesn't...)
-
-See: https://github.com/Audio-Injector/Octo/issues/14

+Subject: [PATCH 437/725] staging: bcm2835-audio: Clean up mutex locks
+
+commit ce4bb1aa271a97047b80ac917a5d91b54925913b upstream.
+
+snd-bcm2835 driver takes the lock with mutex_lock_interruptible() in
+all places, which don't make sense.  Replace them with the simple
+mutex_lock().
+
+Also taking a mutex lock right after creating it for each PCM object
+is nonsense, too.  It cannot be racy at that point.  We can get rid of
+it.
+
+Last but not least, initializing chip->audio_mutex at each place is
+error-prone.  Initialize properly at creating the chip object in
+snd_bcm2835_create() instead.

+ ctls
+
+commit ab91e26229eaca2832df51e13c1285aea3be33ab upstream.
+
+The "IEC958 Playback Stream" control does basically the very same
+thing as "IEC958 Playback Default" redundantly.  The former should
+have been stream-specific and restored after closing the stream, but
+we don't do in that way.
+
+Since it's nothing but confusion, remove this fake.

-
-commit ce4bb1aa271a97047b80ac917a5d91b54925913b upstream.
-
-snd-bcm2835 driver takes the lock with mutex_lock_interruptible() in
-all places, which don't make sense.  Replace them with the simple
-mutex_lock().
-
-Also taking a mutex lock right after creating it for each PCM object
-is nonsense, too.  It cannot be racy at that point.  We can get rid of
-it.
-
-Last but not least, initializing chip->audio_mutex at each place is
-error-prone.  Initialize properly at creating the chip object in
-snd_bcm2835_create() instead.

+Subject: [PATCH 440/725] staging: bcm2835-audio: Remove redundant substream
+ mask checks
+
+commit 14b1f4cba853a11c7b381ad919622f38eb194bd7 upstream.
+
+The avail_substreams bit mask is checked for the possible racy
+accesses, but this cannot happen in practice; i.e. the assignment and
+the check are superfluous.
+
+Let's rip them off.

+Subject: [PATCH 441/725] staging: bcm2835-audio: Fix mute controls, volume
+ handling cleanup
+
+commit 495e5a0d83d3902c741771f267a702ae19da8ab6 upstream.
+
+In the current code, the mute control is dealt in a special manner,
+modifying the current volume and saving the old volume, etc.  This is
+inconsistent (e.g. change the volume while muted, then unmute), and
+way too complex.
+
+Also, the whole volume handling code has conversion between ALSA
+volume and raw volume values, which can lead to another
+inconsistency and complexity.
+
+This patch simplifies these points:
+- The ALSA volume value is saved in chip->volume
+- volume->mute saves the mute state
+- The mute state is evaluated only when the actual volume is passed to
+  the hardware, bcm2835_audio_set_ctls()

- ctls
-
-commit ab91e26229eaca2832df51e13c1285aea3be33ab upstream.
-
-The "IEC958 Playback Stream" control does basically the very same
-thing as "IEC958 Playback Default" redundantly.  The former should
-have been stream-specific and restored after closing the stream, but
-we don't do in that way.
-
-Since it's nothing but confusion, remove this fake.

+ calls
+
+commit 124950ebe9fa8547c59e8d4acc8d6c59e6278ed6 upstream.
+
+bcm2835_audio_setup(), bcm2835_audio_flush_buffers() and
+bcm2835_audio_flush_playback_buffers() functions do implement
+nothing.
+
+Also, bcm2835_audio_set_ctls() is already called inside
+bcm2835_audio_set_params(), so the later call is superfluous.
+
+This patch removes these superfluous implementations.

+All the alsa_stream->open flag checks in the current code are

+Subject: [PATCH 444/725] staging: bcm2835-audio: Drop useless running flag and
+ check
+
+commit 02f2376321d75e78117f39ff81f215254ee6b4ef upstream.
+
+The running flag of alsa_stream is basically useless.  The running
+state is strictly controlled in ALSA PCM core side, hence the check in
+PCM trigger and close callbacks are superfluous.
+
+Also, the prefill ack at trigger start became superfluous nowadays
+with the ALSA PCM core update.
+
+Let's rip them off.

-Subject: [PATCH 444/703] staging: bcm2835-audio: Fix mute controls, volume
- handling cleanup
-
-commit 495e5a0d83d3902c741771f267a702ae19da8ab6 upstream.
-
-In the current code, the mute control is dealt in a special manner,
-modifying the current volume and saving the old volume, etc.  This is
-inconsistent (e.g. change the volume while muted, then unmute), and
-way too complex.
-
-Also, the whole volume handling code has conversion between ALSA
-volume and raw volume values, which can lead to another
-inconsistency and complexity.
-
-This patch simplifies these points:
-- The ALSA volume value is saved in chip->volume
-- volume->mute saves the mute state
-- The mute state is evaluated only when the actual volume is passed to
-  the hardware, bcm2835_audio_set_ctls()

+Subject: [PATCH 445/725] staging: bcm2835-audio: Fix incorrect draining
+ handling
+
+commit 7d2a91f5f1bcf08ca257bcf1ed9721fcd341f834 upstream.
+
+The handling of SNDRV_PCM_TRIGGER_STOP at the trigger callback is
+incorrect: when the STOP is issued, the driver is supposed to drop the
+stream immediately.  Meanwhile bcm2835 driver checks the DRAINING
+state and tries to issue some different command.
+
+This patch straightens things a bit, dropping the incorrect state
+checks.  The draining behavior would be still not perfect at this
+point, but will be improved in a later patch.

-commit 124950ebe9fa8547c59e8d4acc8d6c59e6278ed6 upstream.
-
-bcm2835_audio_setup(), bcm2835_audio_flush_buffers() and
-bcm2835_audio_flush_playback_buffers() functions do implement
-nothing.
-
-Also, bcm2835_audio_set_ctls() is already called inside
-bcm2835_audio_set_params(), so the later call is superfluous.
-
-This patch removes these superfluous implementations.

-
-commit 02f2376321d75e78117f39ff81f215254ee6b4ef upstream.
-
-The running flag of alsa_stream is basically useless.  The running
-state is strictly controlled in ALSA PCM core side, hence the check in
-PCM trigger and close callbacks are superfluous.
-
-Also, the prefill ack at trigger start became superfluous nowadays
-with the ALSA PCM core update.
-
-Let's rip them off.

-Subject: [PATCH 448/703] staging: bcm2835-audio: Fix incorrect draining
- handling
-
-commit 7d2a91f5f1bcf08ca257bcf1ed9721fcd341f834 upstream.
-
-The handling of SNDRV_PCM_TRIGGER_STOP at the trigger callback is
-incorrect: when the STOP is issued, the driver is supposed to drop the
-stream immediately.  Meanwhile bcm2835 driver checks the DRAINING
-state and tries to issue some different command.
-
-This patch straightens things a bit, dropping the incorrect state
-checks.  The draining behavior would be still not perfect at this
-point, but will be improved in a later patch.

+
+commit 055e1c330d04df87d4730a5db837161c11ddaafc upstream.
+
+These debug messages worsen the code readability a lot while they give
+little debuggability (which we already have via tracing, in anyway).
+
+Let's clean them up.  This allows us to reduce the
+snd_bcm2835_pcm_lib_ioctl() function to be a direct call of the
+snd_pcm_lib_ioctl callback (like most other drivers do), too.

+ during prepare
+
+commit f0eb15d055380ff127e5f12c8fad2b36bdb3c006 upstream.
+
+The chip->audio_mutex is used basically for protecting the opened
+stream assignment, and the prepare callback is irrelevant with it.

+
+It seems that the resolution of vc04 callback is in 10 msec; i.e. the
+minimal period size is also 10 msec.
+
+This patch adds the corresponding hw constraint.

-commit 055e1c330d04df87d4730a5db837161c11ddaafc upstream.
-
-These debug messages worsen the code readability a lot while they give
-little debuggability (which we already have via tracing, in anyway).
-
-Let's clean them up.  This allows us to reduce the
-snd_bcm2835_pcm_lib_ioctl() function to be a direct call of the
-snd_pcm_lib_ioctl callback (like most other drivers do), too.

+
+The bcm2835_audio_instance object contains the array of

+Subject: [PATCH 455/725] staging: bcm2835-audio: Code refactoring of vchiq
+ accessor codes
+
+commit 769a8e9bf5cf39813f52962fdafdf7e4d52ad585 upstream.
+
+This is a cleanup and code refactoring in bcm2835-vchiq.c.
+
+The major code changes are to provide local helpers for easier use of
+lock / unlock, and message passing with/without response wait.  This
+allows us to reduce lots of open codes.
+
+Also, the max packet is set at opening the stream, not at each time
+when the write gets called.

+Subject: [PATCH 456/725] staging: bcm2835-audio: Operate non-atomic PCM ops
+
+commit 5c7883e5f27e829f3f3a2ba174d4a724bfd5f026 upstream.
+
+This is the most significant part in the patch series.
+
+The bcm2835-audio driver used to queue the commands to vc04 core via
+workqueue, but basically the whole accesses to vc04 core are done in
+the sleepable context, including the callback calls.  In such a case,
+rewriting the code using non-atomic PCM ops will simplify the logic a
+lot.
+
+This patch does it: all workqueue are gone and each former-work
+implementation is now directly called from PCM ops like trigger and
+write transfer.
+
+Along with it, the DMA position updater, bcm2835_playback_fifo(), was
+also rewritten to use a simpler logic.  Now it handles the XRUN and
+draining properly by calling snd_pcm_stop() conditionally.
+
+The current position is kept in atomic_t value so that it can be read
+concurrently from the pointer callback.
+
+Also, the bcm2835_audio_instance object is allocated at the beginning
+of bcm2835_audio_open().  This makes the resource management clearer.

-Subject: [PATCH 457/703] staging: bcm2835-audio: Make single vchi handle
-
-commit 326a6edcb2ada56375bd7d3fc24c83f58e8da7f3 upstream.
-
-The bcm2835_audio_instance object contains the array of
-VCHI_SERVICE_HANDLE_T, while the code assumes and uses only the first
-element explicitly.  Let's reduce to a single vchi handle for
-simplifying the code.

+
+commit 898001a0c845cefe5d47d133485712412853f0a8 upstream.
+
+Instead of allocating a separate snd_device object, let snd_card_new()
+allocate the private resource.  This simplifies the code.

-Subject: [PATCH 458/703] staging: bcm2835-audio: Code refactoring of vchiq
- accessor codes
-
-commit 769a8e9bf5cf39813f52962fdafdf7e4d52ad585 upstream.
-
-This is a cleanup and code refactoring in bcm2835-vchiq.c.
-
-The major code changes are to provide local helpers for easier use of
-lock / unlock, and message passing with/without response wait.  This
-allows us to reduce lots of open codes.
-
-Also, the max packet is set at opening the stream, not at each time
-when the write gets called.

+Date: Tue, 4 Sep 2018 17:58:51 +0200
+Subject: [PATCH 458/725] staging: bcm2835-audio: Use standard error print
+ helpers
+
+commit b7584b64168208ebc14160770c0966b8b12fc16b upstream.
+
+For making the whole code more consistent, replace the home-made debug
+print macros with the standard dev_err() & co.

-Subject: [PATCH 459/703] staging: bcm2835-audio: Operate non-atomic PCM ops
-
-commit 5c7883e5f27e829f3f3a2ba174d4a724bfd5f026 upstream.
-
-This is the most significant part in the patch series.
-
-The bcm2835-audio driver used to queue the commands to vc04 core via
-workqueue, but basically the whole accesses to vc04 core are done in
-the sleepable context, including the callback calls.  In such a case,
-rewriting the code using non-atomic PCM ops will simplify the logic a
-lot.
-
-This patch does it: all workqueue are gone and each former-work
-implementation is now directly called from PCM ops like trigger and
-write transfer.
-
-Along with it, the DMA position updater, bcm2835_playback_fifo(), was
-also rewritten to use a simpler logic.  Now it handles the XRUN and
-draining properly by calling snd_pcm_stop() conditionally.
-
-The current position is kept in atomic_t value so that it can be read
-concurrently from the pointer callback.
-
-Also, the bcm2835_audio_instance object is allocated at the beginning
-of bcm2835_audio_open().  This makes the resource management clearer.

+
+commit ad29c6e6cbf6f2af7362b043adad51a3be3d39c7 upstream.
+
+The memory access to the pages allocated with
+SNDRV_DMA_TYPE_CONTINUOUS are basically non-coherent, and it becomes a
+problem when a process accesses via mmap.
+
+For the more consistent access, use the device coherent memory, just
+by replacing the call pattern in the allocator helpers.
+
+The only point we need to be careful for is the device object passed
+there; since bcm2835-audio driver creates fake devices and each card
+is created on top of that, we need to pass its parent device as the
+real device object.

+
+commit b59d6a5f73501f74848d6700101e7736afe3d54a upstream.
+
+The recent ALSA PCM core supports the SNDRV_PCM_INFO_SYNC_APPLPTR flag
+indicating that the driver needs the ack call at each appl_ptr
+update.  This is requirement for the indirect PCM implementations like
+bcm2835-audio driver, too.

-
-commit ad29c6e6cbf6f2af7362b043adad51a3be3d39c7 upstream.
-
-The memory access to the pages allocated with
-SNDRV_DMA_TYPE_CONTINUOUS are basically non-coherent, and it becomes a
-problem when a process accesses via mmap.
-
-For the more consistent access, use the device coherent memory, just
-by replacing the call pattern in the allocator helpers.
-
-The only point we need to be careful for is the device object passed
-there; since bcm2835-audio driver creates fake devices and each card
-is created on top of that, we need to pass its parent device as the
-real device object.

+ management
+
+commit 872ae2d63d516a2a3b9c833d8685afcfa7814542 upstream.
+
+Instead of creating a dummy child device to manage the card object,
+just use devm stuff directly for releasing with snd_card_free().
+This results in a lot of code reduction.
+
+Since the dummy child devices are gone, the device object to be passed
+to the memory allocator needs to be adjusted as well.

+ definitions
+
+commit a90d8f49cc7fd7220aa24b85fc74ef3cfd62b96f upstream.
+
+The device communicates with the audio core using FOURCC codes. The
+driver was generating them using different macros/expressions. We now
+use the same macro to create them and centralize all the definitions.

+Subject: [PATCH 467/725] staging: bcm2835-audio: don't initialize memory twice
+
+commit 2e5f59fb77397cab3bc3d156e8be4164a67d32ef upstream.
+
+The memory is being allocated with devres_alloc(), wich ultimately uses
+__GFP_ZERO to call kmalloc. We don't need to zero the memory area again
+in bcm2835-audio.

-Subject: [PATCH 468/703] staging: bcm2835-audio: Simplify card object
- management
-
-commit 872ae2d63d516a2a3b9c833d8685afcfa7814542 upstream.
-
-Instead of creating a dummy child device to manage the card object,
-just use devm stuff directly for releasing with snd_card_free().
-This results in a lot of code reduction.
-
-Since the dummy child devices are gone, the device object to be passed
-to the memory allocator needs to be adjusted as well.

+
+When it comes to declaring variables it's preferred, when possible, to

+
+Also, removes some comments that were useless.

+commit 9c2eaf7da855d314a369d48b9cbf8ac80717a1d0 upstream.
+
+In this case explicitly naming the union doesn't help overall code

+
+commit 01ec7398c56e8f1b903ecb3c5c75400e263eef43 upstream.
+
+The following tasks were completed or not the right solution:
+
+1/2- Not the proper solution, we should register a platform device in
+vchiq the same way it's done with bcm2835-camera as commented here:
+https://lkml.org/lkml/2018/10/16/1131
+
+2/3- Fixed by Takashi Iwai here: https://lkml.org/lkml/2018/9/4/587
+
+Also, adds a new task as per mailing list conversation.

+Subject: [PATCH 473/725] staging: bcm2835-audio: interpolate audio delay
+
+commit a105a3a72824e0ac685a0711a67e4dbe29de62d0 upstream.
+
+When the BCM2835 audio output is used, userspace sees a jitter up to 10ms
+in the audio position, aka "delay" -- the number of frames that must
+be output before a new frame would be played.
+Make this a bit nicer for userspace by interpolating the position
+using the CPU clock.
+The overhead is small -- an extra ktime_get() every time a GPU message
+is sent -- and another call and a few calculations whenever the delay
+is sought from userland.
+At 48,000 frames per second, i.e. approximately 20 microseconds per
+frame, it would take a clock inaccuracy of
+20 microseconds in 10 milliseconds -- 2,000 parts per million --
+to result in an inaccurate estimate, whereas
+crystal- or resonator-based clocks typically have an
+inaccuracy of 10s to 100s of parts per million.

+Just like the bcm2835-video make this a platform driver which is probed

-
-commit a105a3a72824e0ac685a0711a67e4dbe29de62d0 upstream.
-
-When the BCM2835 audio output is used, userspace sees a jitter up to 10ms
-in the audio position, aka "delay" -- the number of frames that must
-be output before a new frame would be played.
-Make this a bit nicer for userspace by interpolating the position
-using the CPU clock.
-The overhead is small -- an extra ktime_get() every time a GPU message
-is sent -- and another call and a few calculations whenever the delay
-is sought from userland.
-At 48,000 frames per second, i.e. approximately 20 microseconds per
-frame, it would take a clock inaccuracy of
-20 microseconds in 10 milliseconds -- 2,000 parts per million --
-to result in an inaccurate estimate, whereas
-crystal- or resonator-based clocks typically have an
-inaccuracy of 10s to 100s of parts per million.

+dwc_otg allocates DMA-coherent buffers in atomic context for misaligned

+increase this for now to prevent failures seen on 4.19 with multiple

-
-commit 438fc48260a0afc4cee733e5bc20234ff2bbef56 upstream.
-
-Just like the bcm2835-video make this a platform driver which is probed
-by vchiq. In order to change the number of channels use a module
-parameter instead, but use the maximum as default.

-Subject: [PATCH 481/703] dts: Increase default coherent pool size
-
-dwc_otg allocates DMA-coherent buffers in atomic context for misaligned
-transfer buffers. The pool that these allocations come from is set up
-at boot-time but can be overridden by a commandline parameter -
-increase this for now to prevent failures seen on 4.19 with multiple
-USB Ethernet devices.

+ padding bytes
+
+dwc_otg requires a 32-bit aligned buffer start address, otherwise
+expensive bounce buffers are used. The LAN951x hardware can skip up to
+3 bytes between the TX header and the start of frame data, which can
+be used to force alignment of the URB passed to dwc_otg.

-Subject: [PATCH 484/703] smsc95xx: dynamically fix up TX buffer alignment with
- padding bytes
-
-dwc_otg requires a 32-bit aligned buffer start address, otherwise
-expensive bounce buffers are used. The LAN951x hardware can skip up to
-3 bytes between the TX header and the start of frame data, which can
-be used to force alignment of the URB passed to dwc_otg.

-The ISP has no need for heights to be a multiple of macroblock

+
+The driver tries a cma_alloc to avoid using gpu_mem, but should

+Subject: [PATCH 495/725] w1: ds2408: reset on output_write retry with readback
+
+commit 49695ac46861180baf2b2b92c62da8619b6bf28f upstream.
+
+When we have success in 'Channel Access Write' but reading back latch
+states fails, a write is retried without doing a proper slave reset.
+This leads to protocol errors as the slave treats the next 'Channel
+Access Write' as the continuation of previous command.
+
+This commit is fixing this by making sure if the retry loop re-runs, a
+reset is performed, whatever the failure (CONFIRM_BYTE or the read
+back).
+
+The loop was quite due for a cleanup and this change mandated it. By
+isolating the CONFIG_W1_SLAVE_DS2408_READBACK case into it's own
+function, we vastly reduce the visual and branching(runtime and
+compile-time) noise.

+Subject: [PATCH 496/725] w1: ds2482: cosmetic fixes after 54865314f5a1
+
+commit 5cb27d30fc3a281e830a2099d520b469e2b82008 upstream.
+
+We have a helper function ds2482_calculate_config() which is calculating
+the config value, so just use it instead of passing the same variable
+in all calls to this function.
+
+Also fixes the placement of module parameters to match with:

-Subject: [PATCH 499/703] w1: ds2408: reset on output_write retry with readback
-
-commit 49695ac46861180baf2b2b92c62da8619b6bf28f upstream.
-
-When we have success in 'Channel Access Write' but reading back latch
-states fails, a write is retried without doing a proper slave reset.
-This leads to protocol errors as the slave treats the next 'Channel
-Access Write' as the continuation of previous command.
-
-This commit is fixing this by making sure if the retry loop re-runs, a
-reset is performed, whatever the failure (CONFIRM_BYTE or the read
-back).
-
-The loop was quite due for a cleanup and this change mandated it. By
-isolating the CONFIG_W1_SLAVE_DS2408_READBACK case into it's own
-function, we vastly reduce the visual and branching(runtime and
-compile-time) noise.

+Subject: [PATCH 500/725] Bluetooth: Check key sizes only when Secure Simple
+ Pairing is enabled
+
+The encryption is only mandatory to be enforced when both sides are using
+Secure Simple Pairing and this means the key size check makes only sense
+in that case.
+
+On legacy Bluetooth 2.0 and earlier devices like mice the encryption was
+optional and thus causing an issue if the key size check is not bound to
+using Secure Simple Pairing.
+
+Fixes: d5bb334a8e17 ("Bluetooth: Align minimum encryption key size for LE and BR/EDR connections")

-commit 5cb27d30fc3a281e830a2099d520b469e2b82008 upstream.
-
-We have a helper function ds2482_calculate_config() which is calculating
-the config value, so just use it instead of passing the same variable
-in all calls to this function.
-
-Also fixes the placement of module parameters to match with:

-Subject: [PATCH 504/703] Bluetooth: Check key sizes only when Secure Simple
- Pairing is enabled
-
-The encryption is only mandatory to be enforced when both sides are using
-Secure Simple Pairing and this means the key size check makes only sense
-in that case.
-
-On legacy Bluetooth 2.0 and earlier devices like mice the encryption was
-optional and thus causing an issue if the key size check is not bound to
-using Secure Simple Pairing.

-Fixes: d5bb334a8e17 ("Bluetooth: Align minimum encryption key size for LE and BR/EDR connections")

+Subject: [PATCH 504/725] overlays: Standardise on compatible="brcm,bcm2835"
+
+Curb the proliferation of compatible string combinations by
+standardising on "brcm,bcm2835" to denote BCM2835 and its descendants.
+
+As nothing in the firmware or kernel is checking overlay compatible
+strings, this should be a purely cosmetic change.

+Subject: [PATCH 506/725] BCM270X_DT: Add non-removable clone of mmc node
+
+non-removable is a boolean property, and as such can't be unset by an
+overlay if it is set in a base DTB. Until now the workaround for this
+problem has been for overlays to clone non-removable nodes without
+the offending property, but this involves a lot of unnecessary
+replication. Instead, add a clone of the mmc node with non-removable
+already set to the base DTB, selecting the required version using
+the status properties.

+Subject: [PATCH 507/725] BCM270X_DT: usb: Refactor DTS and overlays
+
+Move the IRQ interrupt declaration in the usb node before the FIQ
+declaration, so that the dwc2 driver will find it. Name the
+interrupts appropriately so that the dwc_otg driver can still find
+them. Then remove the interrupt rewriting from the overlays.

-Subject: [PATCH 508/703] overlays: Standardise on compatible="brcm,bcm2835"
-
-Curb the proliferation of compatible string combinations by
-standardising on "brcm,bcm2835" to denote BCM2835 and its descendants.
-
-As nothing in the firmware or kernel is checking overlay compatible
-strings, this should be a purely cosmetic change.

-Subject: [PATCH 510/703] BCM270X_DT: Add non-removable clone of mmc node
-
-non-removable is a boolean property, and as such can't be unset by an
-overlay if it is set in a base DTB. Until now the workaround for this
-problem has been for overlays to clone non-removable nodes without
-the offending property, but this involves a lot of unnecessary
-replication. Instead, add a clone of the mmc node with non-removable
-already set to the base DTB, selecting the required version using
-the status properties.

+Subject: [PATCH 510/725] BCM270X_DT: Rename Pi Zero W DT files
+
+The downtream Pi Zero W dts file uses the digit 0, whereas upstream
+chose to spell it out - "zero-w". The firmware has, for a long time,
+looked for bcm2708-rpi-zero-w.dtb first before falling back to the
+numerical version. Therefore it is better to follow upstream and
+make the switch to "bcm2708-rpi-zero-w".
+
+At the same time, remove some overrides that duplicate values
+inherited from the shared .dtsi files.

-Subject: [PATCH 511/703] BCM270X_DT: usb: Refactor DTS and overlays
-
-Move the IRQ interrupt declaration in the usb node before the FIQ
-declaration, so that the dwc2 driver will find it. Name the
-interrupts appropriately so that the dwc_otg driver can still find
-them. Then remove the interrupt rewriting from the overlays.

-Subject: [PATCH 514/703] BCM270X_DT: Rename Pi Zero W DT files
-
-The downtream Pi Zero W dts file uses the digit 0, whereas upstream
-chose to spell it out - "zero-w". The firmware has, for a long time,
-looked for bcm2708-rpi-zero-w.dtb first before falling back to the
-numerical version. Therefore it is better to follow upstream and
-make the switch to "bcm2708-rpi-zero-w".
-
-At the same time, remove some overrides that duplicate values
-inherited from the shared .dtsi files.

+Subject: [PATCH 517/725] w1: w1-gpio: Make GPIO an output for strong pullup

+The logic to drive the data line high to implement a strong pullup
+assumed that the pin was already an output - setting a value does
+not change an input.

- to MMAL usec
-
-V4L2 uses nsecs, whilst MMAL uses usecs, but the code wasn't converting
-between them. This upsets video encode rate control.

+Subject: [PATCH 520/725] i2c: bcm2835: Model Divider in CCF
+
+Commit bebff81fb8b9216eb4fba22cf910553621ae3477 upstream.
+
+Model the I2C bus clock divider as a part of the Core Clock Framework.
+Primarily this removes the clk_get_rate() call from each transfer.
+This call causes problems for slave drivers that themselves have
+internal clock components that are controlled by an I2C interface.
+When the slave's internal clock component is prepared, the prepare
+lock is obtained, and it makes calls to the I2C subsystem to
+command the hardware to activate the clock.  In order to perform
+the I2C transfer, this driver sets the divider, which requires
+it to get the parent clock rate, which it does with clk_get_rate().
+Unfortunately, this function will try to take the clock prepare
+lock, which is already held by the slave's internal clock calls
+creating a deadlock.
+
+Modeling the divider in the CCF natively removes this dependency
+and the divider value is only set upon changing the bus clock
+frequency or changes in the parent clock that cascade down to this
+divisor.  This obviates the need to set the divider with every
+transfer and avoids the deadlock described above.  It also should
+provide better clock debugging and save a few cycles on each
+transfer due to not having to recalcuate the divider value.

+The PL011 register space includes all necessary status bits to

+to an interrupt. Therefore, multiple instances of the device could
+be serviced by a single shared interrupt, which is the case on BCM7211.

+Subject: [PATCH 524/725] ARM: bcm283x: Extend the WDT DT node out to cover the
+ whole PM block. (v4)
+
+It was covering part of the PM block's range, up to the WDT regs.  To
+support the rest of the PM block's functionality, we need the full
+register range plus the AXI Async Bridge regs for PM sequencing.
+
+This doesn't convert any of the consumers over to the new binding yet,
+since we will need to be careful in coordinating our usage of firmware
+services that might power domains on and off versus the bcm2835-pm
+driver's access of those same domains.

-Subject: [PATCH 524/703] i2c: bcm2835: Model Divider in CCF
-
-Commit bebff81fb8b9216eb4fba22cf910553621ae3477 upstream.
-
-Model the I2C bus clock divider as a part of the Core Clock Framework.
-Primarily this removes the clk_get_rate() call from each transfer.
-This call causes problems for slave drivers that themselves have
-internal clock components that are controlled by an I2C interface.
-When the slave's internal clock component is prepared, the prepare
-lock is obtained, and it makes calls to the I2C subsystem to
-command the hardware to activate the clock.  In order to perform
-the I2C transfer, this driver sets the divider, which requires
-it to get the parent clock rate, which it does with clk_get_rate().
-Unfortunately, this function will try to take the clock prepare
-lock, which is already held by the slave's internal clock calls
-creating a deadlock.
-
-Modeling the divider in the CCF natively removes this dependency
-and the divider value is only set upon changing the bus clock
-frequency or changes in the parent clock that cascade down to this
-divisor.  This obviates the need to set the divider with every
-transfer and avoids the deadlock described above.  It also should
-provide better clock debugging and save a few cycles on each
-transfer due to not having to recalcuate the divider value.

-Subject: [PATCH 526/703] tty: amba-pl011: allow shared interrupt
-
-The PL011 register space includes all necessary status bits to
-determine whether a device instance requires handling in response
-to an interrupt. Therefore, multiple instances of the device could
-be serviced by a single shared interrupt, which is the case on BCM7211.

-Subject: [PATCH 528/703] ARM: bcm283x: Extend the WDT DT node out to cover the
- whole PM block. (v4)
-
-It was covering part of the PM block's range, up to the WDT regs.  To
-support the rest of the PM block's functionality, we need the full
-register range plus the AXI Async Bridge regs for PM sequencing.
-
-This doesn't convert any of the consumers over to the new binding yet,
-since we will need to be careful in coordinating our usage of firmware
-services that might power domains on and off versus the bcm2835-pm
-driver's access of those same domains.

+The ioremapping creates mappings within the vmalloc area. The

+requested explicit virtual address is between VMALLOC_START and
+VMALLOC_END. As there is no reason to have any correlation between
+the physical and virtual addresses, put the required mappings at

+ driver
+
+This commit adds the basic Broadcom STB PCIe controller.  Missing is
+the ability to process MSI and also handle dma-ranges for inbound
+memory accesses.  These two functionalities are added in subsequent
+commits.
+
+The PCIe block contains an MDIO interface.  This is a local interface
+only accessible by the PCIe controller.  It cannot be used or shared
+by any other HW.  As such, the small amount of code for this
+controller is included in this driver as there is little upside to put
+it elsewhere.

+Subject: [PATCH 531/725] PCI: brcmstb: Add dma-range mapping for inbound
+ traffic
+
+The Broadcom STB PCIe host controller is intimately related to the
+memory subsystem.  This close relationship adds complexity to how cpu
+system memory is mapped to PCIe memory.  Ideally, this mapping is an
+identity mapping, or an identity mapping off by a constant.  Not so in
+this case.
+
+Consider the Broadcom reference board BCM97445LCC_4X8 which has 6 GB
+of system memory.  Here is how the PCIe controller maps the
+system memory to PCIe memory:
+
+  memc0-a@[        0....3fffffff] <=> pci@[        0....3fffffff]
+  memc0-b@[100000000...13fffffff] <=> pci@[ 40000000....7fffffff]
+  memc1-a@[ 40000000....7fffffff] <=> pci@[ 80000000....bfffffff]
+  memc1-b@[300000000...33fffffff] <=> pci@[ c0000000....ffffffff]
+  memc2-a@[ 80000000....bfffffff] <=> pci@[100000000...13fffffff]
+  memc2-b@[c00000000...c3fffffff] <=> pci@[140000000...17fffffff]
+
+Although there are some "gaps" that can be added between the
+individual mappings by software, the permutation of memory regions for
+the most part is fixed by HW.  The solution of having something close
+to an identity mapping is not possible.
+
+The idea behind this HW design is that the same PCIe module can
+act as an RC or EP, and if it acts as an EP it concatenates all
+of system memory into a BAR so anything can be accessed.  Unfortunately,
+when the PCIe block is in the role of an RC it also presents this
+"BAR" to downstream PCIe devices, rather than offering an identity map
+between its system memory and PCIe space.
+
+Suppose that an endpoint driver allocs some DMA memory.  Suppose this
+memory is located at 0x6000_0000, which is in the middle of memc1-a.
+The driver wants a dma_addr_t value that it can pass on to the EP to
+use.  Without doing any custom mapping, the EP will use this value for
+DMA: the driver will get a dma_addr_t equal to 0x6000_0000.  But this
+won't work; the device needs a dma_addr_t that reflects the PCIe space
+address, namely 0xa000_0000.
+
+So, essentially the solution to this problem must modify the
+dma_addr_t returned by the DMA routines routines.  There are two
+ways (I know of) of doing this:
+
+(a) overriding/redefining the dma_to_phys() and phys_to_dma() calls
+that are used by the dma_ops routines.  This is the approach of
+
+	arch/mips/cavium-octeon/dma-octeon.c
+
+In ARM and ARM64 these two routines are defiend in asm/dma-mapping.h
+as static inline functions.
+
+(b) Subscribe to a notifier that notifies when a device is added to a
+bus.  When this happens, set_dma_ops() can be called for the device.
+This method is mentioned in:
+
+    http://lxr.free-electrons.com/source/drivers/of/platform.c?v=3.16#L152
+
+where it says as a comment
+
+    "In case if platform code need to use own special DMA
+    configuration, it can use Platform bus notifier and
+    handle BUS_NOTIFY_ADD_DEVICE event to fix up DMA
+    configuration."
+
+Solution (b) is what this commit does.  It uses its own set of
+dma_ops which are wrappers around the arch_dma_ops.  The
+wrappers translate the dma addresses before/after invoking
+the arch_dma_ops, as appropriate.

+From 2f802e11ea7ca4f7c688ecc64019bec25a5e62a1 Mon Sep 17 00:00:00 2001

+Date: Tue, 19 Feb 2019 22:06:59 +0000
+Subject: [PATCH 532/725] PCI: brcmstb: Add MSI capability
+
+This commit adds MSI to the Broadcom STB PCIe host controller. It does
+not add MSIX since that functionality is not in the HW.  The MSI
+controller is physically located within the PCIe block, however, there
+is no reason why the MSI controller could not be moved elsewhere in
+the future.
+
+Since the internal Brcmstb MSI controller is intertwined with the PCIe
+controller, it is not its own platform device but rather part of the
+PCIe platform device.

-Subject: [PATCH 532/703] arm: bcm2835: Fix FIQ early ioremap
-
-The ioremapping creates mappings within the vmalloc area. The
-equivalent early function, create_mapping, now checks that the
-requested explicit virtual address is between VMALLOC_START and
-VMALLOC_END. As there is no reason to have any correlation between
-the physical and virtual addresses, put the required mappings at
-VMALLOC_START and above.

-
-The change which introduced CONFIG_BCM2835_FAST_MEMCPY unconditionally
-changed the behaviour of arm_copy_from_user. The page pinning code
-is not safe on ARMv7 if LPAE & high memory is enabled and causes
-crashes which look like PTE corruption.
-
-Make __copy_from_user_memcpy conditional on CONFIG_2835_FAST_MEMCPY=y
-which is really an ARMv6 / Pi1 optimization and not necessary on newer
-ARM processors.

++Brcmstb PCIe Host Controller Device Tree Bindings
++
++Required Properties:
++- compatible
++  "brcm,bcm7425-pcie" -- for 7425 family MIPS-based SOCs.
++  "brcm,bcm7435-pcie" -- for 7435 family MIPS-based SOCs.
++  "brcm,bcm7445-pcie" -- for 7445 and later ARM based SOCs (not including
++      the 7278).
++  "brcm,bcm7278-pcie"  -- for 7278 family ARM-based SOCs.
++
++- reg -- the register start address and length for the PCIe reg block.
++- interrupts -- two interrupts are specified; the first interrupt is for
++     the PCI host controller and the second is for MSI if the built-in
++     MSI controller is to be used.
++- interrupt-names -- names of the interrupts (above): "pcie" and "msi".
++- #address-cells -- set to <3>.
++- #size-cells -- set to <2>.
++- #interrupt-cells: set to <1>.
++- interrupt-map-mask and interrupt-map, standard PCI properties to define the
++     mapping of the PCIe interface to interrupt numbers.
++- ranges: ranges for the PCI memory and I/O regions.
++- linux,pci-domain -- should be unique per host controller.
++
++Optional Properties:
++- clocks -- phandle of pcie clock.
++- clock-names -- set to "sw_pcie" if clocks is used.
++- dma-ranges -- Specifies the inbound memory mapping regions when
++     an "identity map" is not possible.
++- msi-controller -- this property is typically specified to have the
++     PCIe controller use its internal MSI controller.
++- msi-parent -- set to use an external MSI interrupt controller.
++- brcm,enable-ssc -- (boolean) indicates usage of spread-spectrum clocking.
++- max-link-speed --  (integer) indicates desired generation of link:
++     1 => 2.5 Gbps (gen1), 2 => 5.0 Gbps (gen2), 3 => 8.0 Gbps (gen3).

-Subject: [PATCH 534/703] PCI: brcmstb: Add Broadcom STB PCIe host controller
- driver
-
-This commit adds the basic Broadcom STB PCIe controller.  Missing is
-the ability to process MSI and also handle dma-ranges for inbound
-memory accesses.  These two functionalities are added in subsequent
-commits.
-
-The PCIe block contains an MDIO interface.  This is a local interface
-only accessible by the PCIe controller.  It cannot be used or shared
-by any other HW.  As such, the small amount of code for this
-controller is included in this driver as there is little upside to put
-it elsewhere.

-Subject: [PATCH 535/703] PCI: brcmstb: Add dma-range mapping for inbound
- traffic
-
-The Broadcom STB PCIe host controller is intimately related to the
-memory subsystem.  This close relationship adds complexity to how cpu
-system memory is mapped to PCIe memory.  Ideally, this mapping is an
-identity mapping, or an identity mapping off by a constant.  Not so in
-this case.
-
-Consider the Broadcom reference board BCM97445LCC_4X8 which has 6 GB
-of system memory.  Here is how the PCIe controller maps the
-system memory to PCIe memory:
-
-  memc0-a@[        0....3fffffff] <=> pci@[        0....3fffffff]
-  memc0-b@[100000000...13fffffff] <=> pci@[ 40000000....7fffffff]
-  memc1-a@[ 40000000....7fffffff] <=> pci@[ 80000000....bfffffff]
-  memc1-b@[300000000...33fffffff] <=> pci@[ c0000000....ffffffff]
-  memc2-a@[ 80000000....bfffffff] <=> pci@[100000000...13fffffff]
-  memc2-b@[c00000000...c3fffffff] <=> pci@[140000000...17fffffff]
-
-Although there are some "gaps" that can be added between the
-individual mappings by software, the permutation of memory regions for
-the most part is fixed by HW.  The solution of having something close
-to an identity mapping is not possible.
-
-The idea behind this HW design is that the same PCIe module can
-act as an RC or EP, and if it acts as an EP it concatenates all
-of system memory into a BAR so anything can be accessed.  Unfortunately,
-when the PCIe block is in the role of an RC it also presents this
-"BAR" to downstream PCIe devices, rather than offering an identity map
-between its system memory and PCIe space.
-
-Suppose that an endpoint driver allocs some DMA memory.  Suppose this
-memory is located at 0x6000_0000, which is in the middle of memc1-a.
-The driver wants a dma_addr_t value that it can pass on to the EP to
-use.  Without doing any custom mapping, the EP will use this value for
-DMA: the driver will get a dma_addr_t equal to 0x6000_0000.  But this
-won't work; the device needs a dma_addr_t that reflects the PCIe space
-address, namely 0xa000_0000.
-
-So, essentially the solution to this problem must modify the
-dma_addr_t returned by the DMA routines routines.  There are two
-ways (I know of) of doing this:
-
-(a) overriding/redefining the dma_to_phys() and phys_to_dma() calls
-that are used by the dma_ops routines.  This is the approach of
-
-	arch/mips/cavium-octeon/dma-octeon.c
-
-In ARM and ARM64 these two routines are defiend in asm/dma-mapping.h
-as static inline functions.
-
-(b) Subscribe to a notifier that notifies when a device is added to a
-bus.  When this happens, set_dma_ops() can be called for the device.
-This method is mentioned in:
-
-    http://lxr.free-electrons.com/source/drivers/of/platform.c?v=3.16#L152
-
-where it says as a comment
-
-    "In case if platform code need to use own special DMA
-    configuration, it can use Platform bus notifier and
-    handle BUS_NOTIFY_ADD_DEVICE event to fix up DMA
-    configuration."
-
-Solution (b) is what this commit does.  It uses its own set of
-dma_ops which are wrappers around the arch_dma_ops.  The
-wrappers translate the dma addresses before/after invoking
-the arch_dma_ops, as appropriate.

-Subject: [PATCH 536/703] PCI: brcmstb: Add MSI capability
-
-This commit adds MSI to the Broadcom STB PCIe host controller. It does
-not add MSIX since that functionality is not in the HW.  The MSI
-controller is physically located within the PCIe block, however, there
-is no reason why the MSI controller could not be moved elsewhere in
-the future.
-
-Since the internal Brcmstb MSI controller is intertwined with the PCIe
-controller, it is not its own platform device but rather part of the
-PCIe platform device.

-+Brcmstb PCIe Host Controller Device Tree Bindings
-+
-+Required Properties:
-+- compatible
-+  "brcm,bcm7425-pcie" -- for 7425 family MIPS-based SOCs.
-+  "brcm,bcm7435-pcie" -- for 7435 family MIPS-based SOCs.
-+  "brcm,bcm7445-pcie" -- for 7445 and later ARM based SOCs (not including
-+      the 7278).
-+  "brcm,bcm7278-pcie"  -- for 7278 family ARM-based SOCs.
-+
-+- reg -- the register start address and length for the PCIe reg block.
-+- interrupts -- two interrupts are specified; the first interrupt is for
-+     the PCI host controller and the second is for MSI if the built-in
-+     MSI controller is to be used.
-+- interrupt-names -- names of the interrupts (above): "pcie" and "msi".
-+- #address-cells -- set to <3>.
-+- #size-cells -- set to <2>.
-+- #interrupt-cells: set to <1>.
-+- interrupt-map-mask and interrupt-map, standard PCI properties to define the
-+     mapping of the PCIe interface to interrupt numbers.
-+- ranges: ranges for the PCI memory and I/O regions.
-+- linux,pci-domain -- should be unique per host controller.
-+
-+Optional Properties:
-+- clocks -- phandle of pcie clock.
-+- clock-names -- set to "sw_pcie" if clocks is used.
-+- dma-ranges -- Specifies the inbound memory mapping regions when
-+     an "identity map" is not possible.
-+- msi-controller -- this property is typically specified to have the
-+     PCIe controller use its internal MSI controller.
-+- msi-parent -- set to use an external MSI interrupt controller.
-+- brcm,enable-ssc -- (boolean) indicates usage of spread-spectrum clocking.
-+- max-link-speed --  (integer) indicates desired generation of link:
-+     1 => 2.5 Gbps (gen1), 2 => 5.0 Gbps (gen2), 3 => 8.0 Gbps (gen3).

-Subject: [PATCH 542/703] mmc: sdhci-iproc: Add support for emmc2 of the
- BCM2838
-
-The emmc2 interface of the BCM2838 should be integrated in sdhci-iproc
-to avoid code redundancy. Except 32 bit only access no other quirks are
-known yet. Add an additional compatible string for upstream proposal.

+Subject: [PATCH 545/725] net: genet: enable link energy detect powerdown for
+ external PHYs
+
+There are several warts surrounding bcmgenet_mii_probe() as this
+function is called from ndo_open, but it's calling registration-type
+functions. The probe should be called at probe time and refactored
+such that the PHY device data can be extracted to limit the scope
+of this flag to Broadcom PHYs.
+
+For now, pass this flag in as it puts our attached PHY into a low-power
+state when disconnected.

-Subject: [PATCH 548/703] bcmgenet: Better coalescing parameter defaults
-
-Set defaults for TX and RX packet coalescing to be equivalent to:
-
-  # ethtool -C eth0 tx-frames 10
-  # ethtool -C eth0 rx-usecs 50
-
-This may be something we want to set via DT parameters in the
-future.

- external PHYs
-
-There are several warts surrounding bcmgenet_mii_probe() as this
-function is called from ndo_open, but it's calling registration-type
-functions. The probe should be called at probe time and refactored
-such that the PHY device data can be extracted to limit the scope
-of this flag to Broadcom PHYs.
-
-For now, pass this flag in as it puts our attached PHY into a low-power
-state when disconnected.

+Subject: [PATCH 549/725] usb: xhci: Disable the XHCI 5 second timeout
+
+If the VL805 EEPROM has not been programmed then boot will hang for five
+seconds. The timeout seems to be arbitrary and is an unecessary
+delay on the first boot. Remove the timeout.
+
+This is common code and probably can't be upstreamed unless the timeout
+can be configurable somehow or perhaps the XHCI driver can be skipped
+on the first boot.

+ hid.mousepoll behaviour
+
+xHCI creates endpoint contexts directly from the device's endpoint
+data, so submitting URBs with urb->interval different from the hardware
+interval has no effect.
+
+Add an explicit reconfiguration of the endpoint context when requested,
+which will happen only when the interval is different from the cached
+value. In practice, the reconfiguration only happens on the first URB
+submitted for the endpoint.

+Subject: [PATCH 552/725] pinctrl-bcm2835: Add support for BCM2838
+
+GPIO configuration on BCM2838 is largely the same as BCM2835 except for
+the pull up/down configuration. The old mechanism has been replaced
+by new registers which don't require the fixed delay.
+
+Detect BCN2838 at run-time and use the new mechanism. Backwards
+compatibility for the device-tree configuration has been retained.

-Subject: [PATCH 553/703] usb: xhci: Disable the XHCI 5 second timeout
-
-If the VL805 EEPROM has not been programmed then boot will hang for five
-seconds. The timeout seems to be arbitrary and is an unecessary
-delay on the first boot. Remove the timeout.
-
-This is common code and probably can't be upstreamed unless the timeout
-can be configurable somehow or perhaps the XHCI driver can be skipped
-on the first boot.

- hid.mousepoll behaviour
-
-xHCI creates endpoint contexts directly from the device's endpoint
-data, so submitting URBs with urb->interval different from the hardware
-interval has no effect.
-
-Add an explicit reconfiguration of the endpoint context when requested,
-which will happen only when the interval is different from the cached
-value. In practice, the reconfiguration only happens on the first URB
-submitted for the endpoint.

+
+The PM block that the wdt driver was binding to actually has multiple

+DT attachment to a MFD driver and make WDT probe against MFD.

-Subject: [PATCH 556/703] pinctrl-bcm2835: Add support for BCM2838
-
-GPIO configuration on BCM2838 is largely the same as BCM2835 except for
-the pull up/down configuration. The old mechanism has been replaced
-by new registers which don't require the fixed delay.
-
-Detect BCN2838 at run-time and use the new mechanism. Backwards
-compatibility for the device-tree configuration has been retained.

+From 25b7b6863a8dd292fa88309f70c980265b076c4e Mon Sep 17 00:00:00 2001
+From: Eric Anholt <eric@anholt.net>
+Date: Wed, 12 Dec 2018 15:51:48 -0800
+Subject: [PATCH 557/725] soc: bcm: bcm2835-pm: Add support for power domains
+ under a new binding.
+
+This provides a free software alternative to raspberrypi-power.c's
+firmware calls to manage power domains.  It also exposes a reset line,
+where previously the vc4 driver had to try to force power off the
+domain in order to trigger a reset.

+
+The clock driver may probe after ours and so we need to pass the
+-EPROBE_DEFER out.  Fix the other error path while we're here.
+
+v2: Use dom->name instead of dom->gov as the flag for initialized
+    domains, since we aren't setting up a governor.  Make sure to
+    clear ->clk when no clk is present in the DT.

-
-The PM block that the wdt driver was binding to actually has multiple
-features we want to expose (power domains, reset, watchdog).  Move the
-DT attachment to a MFD driver and make WDT probe against MFD.

+Subject: [PATCH 560/725] soc: bcm: bcm2835-pm: Add support for 2711.
+
+Without the actual power management part any more, there's a lot less
+to set up for V3D.  We just need to clear the RSTN field for the power
+domain, and expose the reset controller for toggling it again.
+
+This is definitely incomplete -- the old ISP and H264 is in the old
+bridge, but since we have no consumers of it I've just done the
+minimum to get V3D working.

- under a new binding.
-
-This provides a free software alternative to raspberrypi-power.c's
-firmware calls to manage power domains.  It also exposes a reset line,
-where previously the vc4 driver had to try to force power off the
-domain in order to trigger a reset.

+Subject: [PATCH 562/725] drm/v3d: Fix a use-after-free race accessing the
+ scheduler's fences.
+
+Once we push the job, the scheduler could run it and free it.  So, if
+we want to reference their fences, we need to grab them before then.
+I haven't seen this happen in many days of conformance test runtime,
+but let's still close the race.

+Subject: [PATCH 563/725] drm/v3d: Add a little debugfs entry for measuring the
+ core clock.
+
+This adds just enough performance counter support to measure the
+clock.  We don't have linux kernel drivers for the clock driving the
+HW, and this was useful for determining that the V3D HW is running on
+a slow clock, not that the driver was slow.

-Subject: [PATCH 564/703] soc: bcm: bcm2835-pm: Add support for 2711.
-
-Without the actual power management part any more, there's a lot less
-to set up for V3D.  We just need to clear the RSTN field for the power
-domain, and expose the reset controller for toggling it again.
-
-This is definitely incomplete -- the old ISP and H264 is in the old
-bridge, but since we have no consumers of it I've just done the
-minimum to get V3D working.

+Subject: [PATCH 566/725] drm/v3d: Add support for submitting jobs to the TFU.
+
+The TFU can copy from raster, UIF, and SAND input images to UIF output
+images, with optional mipmap generation.  This will certainly be
+useful for media EGL image input, but is also useful immediately for
+mipmap generation without bogging the V3D core down.
+
+For now we only run the queue 1 job deep, and don't have any hang
+recovery (though I don't think we should need it, with TFU).  Queuing
+multiple jobs in the HW will require synchronizing the YUV coefficient
+regs updates since they don't get FIFOed with the job.
+
+v2: Change the ioctl to IOW instead of IOWR, always set COEF0, explain
+    why TFU is AUTH, clarify the syncing docs, drop the unused TFU
+    interrupt regs (you're expected to use the hub's), don't take
+    &bo->base for NULL bos.
+v3: Fix a little whitespace alignment (noticed by checkpatch), rebase
+    on drm_sched_job_cleanup() changes.

-Subject: [PATCH 566/703] drm/v3d: Fix a use-after-free race accessing the
- scheduler's fences.
-
-Once we push the job, the scheduler could run it and free it.  So, if
-we want to reference their fences, we need to grab them before then.
-I haven't seen this happen in many days of conformance test runtime,
-but let's still close the race.

-Subject: [PATCH 567/703] drm/v3d: Add a little debugfs entry for measuring the
- core clock.
-
-This adds just enough performance counter support to measure the
-clock.  We don't have linux kernel drivers for the clock driving the
-HW, and this was useful for determining that the V3D HW is running on
-a slow clock, not that the driver was slow.

+Subject: [PATCH 569/725] drm/v3d: Add more tracepoints for V3D GPU rendering.
+
+The core scheduler tells us when the job is pushed to the scheduler's
+queue, and I had the job_run functions saying when they actually queue
+the job to the hardware.  By adding tracepoints for the very top of
+the ioctls and the IRQs signaling job completion, "perf record -a -e
+v3d:.\* -e gpu_scheduler:.\* <job>; perf script" gets you a pretty
+decent timeline.

-From 60c65dc612663be7136a19a117cee5d194530600 Mon Sep 17 00:00:00 2001
-From: Eric Anholt <eric@anholt.net>
-Date: Wed, 28 Nov 2018 15:09:25 -0800
-Subject: [PATCH 570/703] drm/v3d: Add support for submitting jobs to the TFU.
-
-The TFU can copy from raster, UIF, and SAND input images to UIF output
-images, with optional mipmap generation.  This will certainly be
-useful for media EGL image input, but is also useful immediately for
-mipmap generation without bogging the V3D core down.
-
-For now we only run the queue 1 job deep, and don't have any hang
-recovery (though I don't think we should need it, with TFU).  Queuing
-multiple jobs in the HW will require synchronizing the YUV coefficient
-regs updates since they don't get FIFOed with the job.
-
-v2: Change the ioctl to IOW instead of IOWR, always set COEF0, explain
-    why TFU is AUTH, clarify the syncing docs, drop the unused TFU
-    interrupt regs (you're expected to use the hub's), don't take
-    &bo->base for NULL bos.
-v3: Fix a little whitespace alignment (noticed by checkpatch), rebase
-    on drm_sched_job_cleanup() changes.
-

+Subject: [PATCH 571/725] drm/v3d: Don't bother flushing L1TD at job start.
+
+This is the write combiner for TMU writes.  You're supposed to flush
+that at job end if you had dirtied any cachelines.  Flushing it at job
+start then doesn't make any sense.

+Subject: [PATCH 572/725] drm/v3d: Drop the wait for L2T flush to complete.
+
+According to Dave, once you've started an L2T flush, all L2T accesses
+will be blocked until the flush completes.  This fixes a consistent
+3-4ms stall between the ioctl and running the job, and 3DMMES Taiji
+goes from 27fps to 110fps.
+
+v2: Leave a note about why we don't need to wait for completion.

-Subject: [PATCH 573/703] drm/v3d: Add more tracepoints for V3D GPU rendering.
-
-The core scheduler tells us when the job is pushed to the scheduler's
-queue, and I had the job_run functions saying when they actually queue
-the job to the hardware.  By adding tracepoints for the very top of
-the ioctls and the IRQs signaling job completion, "perf record -a -e
-v3d:.\* -e gpu_scheduler:.\* <job>; perf script" gets you a pretty
-decent timeline.

-According to Dave, once you've started an L2T flush, all L2T accesses
-will be blocked until the flush completes.  This fixes a consistent
-3-4ms stall between the ioctl and running the job, and 3DMMES Taiji

+Subject: [PATCH 579/725] drm/v3d: Add support for V3D v4.2.
+
+No compatible string for it yet, just the version-dependent changes.
+They've now tied the hub and the core interrupt lines into a single
+interrupt line coming out of the block.  It also turns out I made a
+mistake in modeling the V3D v3.3 and v4.1 bridge as a part of V3D
+itself -- the bridge is going away in favor of an external reset
+controller in a larger HW module.
+
+v2: Use consistent checks for whether we're on 4.2, and fix a leak in
+    an error path.
+v3: Use more general means of determining if the current 4.2 changes
+    are in place, as apparently other platforms may switch back (noted
+    by Dave).  Update the binding doc.

+Subject: [PATCH 580/725] drm/v3d: Don't try to set OVRTMUOUT on V3D 4.x.
+
+The old field is gone and the register now has a different field,
+QRMAXCNT for how many TMU requests get serviced before thread switch.
+We were accidentally reducing it from its default of 0x3 (4 requests)
+to 0x0 (1).
+
+v2: Skip setting the reg at all on 4.x, instead of trying to update
+    only the old field.

-Subject: [PATCH 583/703] drm/v3d: Add support for V3D v4.2.
-
-No compatible string for it yet, just the version-dependent changes.
-They've now tied the hub and the core interrupt lines into a single
-interrupt line coming out of the block.  It also turns out I made a
-mistake in modeling the V3D v3.3 and v4.1 bridge as a part of V3D
-itself -- the bridge is going away in favor of an external reset
-controller in a larger HW module.
-
-v2: Use consistent checks for whether we're on 4.2, and fix a leak in
-    an error path.
-v3: Use more general means of determining if the current 4.2 changes
-    are in place, as apparently other platforms may switch back (noted
-    by Dave).  Update the binding doc.

-If it's off, we know it will be reset on poweron, so the MMU won't

+Subject: [PATCH 588/725] drm/v3d: Refactor job management.
+
+The CL submission had two jobs embedded in an exec struct.  When I
+added TFU support, I had to replicate some of the exec stuff and some
+of the job stuff.  As I went to add CSD, it became clear that actually
+what was in exec should just be in the two CL jobs, and it would let
+us share a lot more code between the 4 queues.

+get implicitly synchronized by their submission order.  If we want to
+allow clever userspace to disable implicit synchronization, we should
+do that under its own submit flag (as amdgpu and lima do).
+
+Note that we currently only implicitly sync for the rendering pass,
+not binning -- if you texture-from-pixmap in the binning vertex shader
+(vertex coordinate generation), you'll miss out on synchronization.
+
+Fixes flickering when multiple clients are running in parallel,
+particularly GL apps and compositors.

-Subject: [PATCH 591/703] drm/v3d: Rename the fence signaled from IRQs to
- "irq_fence".
-
-We have another thing called the "done fence" that tracks when the
-scheduler considers the job done, and having the shared name was
-confusing.

+Subject: [PATCH 591/725] drm/vc4: Make sure that vblank waits work without v3d
+ loaded.
+
+This flag exists to protect legacy drivers, but when vc4's v3d doesn't
+probe, it doesn't get set up by vc4_v3d.c's call of drm_irq_install.
+This resulted in applications running as fast as possible, and laggy
+performance from compton as it had to wait for the latest rendering by
+the application for its presentation.

-Subject: [PATCH 592/703] drm/v3d: Refactor job management.
-
-The CL submission had two jobs embedded in an exec struct.  When I
-added TFU support, I had to replicate some of the exec stuff and some
-of the job stuff.  As I went to add CSD, it became clear that actually
-what was in exec should just be in the two CL jobs, and it would let
-us share a lot more code between the 4 queues.

+Subject: [PATCH 592/725] drm/vc4: Expose the format modifiers for firmware
+ kms.
+
+This should technically not expose VC4_T_TILED on pi4.  However, if we
+don't expose anything, then userspace will assume that display can
+handle whatever modifiers 3d can do (UIF on 2711).  By exposing a
+list, that will get intersected with what 3D can do so that we get T
+tiling for display on 2710 and linear on 2711.

-Subject: [PATCH 593/703] drm/v3d: Add missing implicit synchronization.
-
-It is the expectation of existing userspace (X11 + Mesa, in
-particular) that jobs submitted to the kernel against a shared BO will
-get implicitly synchronized by their submission order.  If we want to
-allow clever userspace to disable implicit synchronization, we should
-do that under its own submit flag (as amdgpu and lima do).
-
-Note that we currently only implicitly sync for the rendering pass,
-not binning -- if you texture-from-pixmap in the binning vertex shader
-(vertex coordinate generation), you'll miss out on synchronization.
-
-Fixes flickering when multiple clients are running in parallel,
-particularly GL apps and compositors.

+Subject: [PATCH 593/725] drm/vc4: Fix vblank timestamping for firmwarekms.
+
+The core doesn't expect a false return from the scanoutpos function in
+normal usage, so we were doing the precise vblank timestamping path
+and thus "immediate" vblank disables (even though firmwarekms can't
+actually disable vblanks interrupts, sigh), and the kernel would get
+confused when getting timestamp info when also turning vblanks back
+on.

+Subject: [PATCH 595/725] drm: vc4: Add an overlay plane to vc4-firmware-kms
+
+This uses a new API that is exposed via the mailbox service
+to stick an element straight on the screen using DispmanX.
+
+The primary and cursor planes have also been switched to using
+the new plane API, and it supports layering based on the DRM
+zpos parameter.

-Subject: [PATCH 595/703] drm/vc4: Make sure that vblank waits work without v3d
- loaded.
-
-This flag exists to protect legacy drivers, but when vc4's v3d doesn't
-probe, it doesn't get set up by vc4_v3d.c's call of drm_irq_install.
-This resulted in applications running as fast as possible, and laggy
-performance from compton as it had to wait for the latest rendering by
-the application for its presentation.

- kms.
-
-This should technically not expose VC4_T_TILED on pi4.  However, if we
-don't expose anything, then userspace will assume that display can
-handle whatever modifiers 3d can do (UIF on 2711).  By exposing a
-list, that will get intersected with what 3D can do so that we get T
-tiling for display on 2710 and linear on 2711.

-Subject: [PATCH 597/703] drm/vc4: Fix vblank timestamping for firmwarekms.
-
-The core doesn't expect a false return from the scanoutpos function in
-normal usage, so we were doing the precise vblank timestamping path
-and thus "immediate" vblank disables (even though firmwarekms can't
-actually disable vblanks interrupts, sigh), and the kernel would get
-confused when getting timestamp info when also turning vblanks back
-on.

-Subject: [PATCH 598/703] gpu: vc4-fkms: Switch to the newer mailbox frame
- buffer API.
-
-The old mailbox FB API was ideally deprecated but still used by
-the FKMS driver.
-Update to the newer API.
-
-NB This needs current firmware that accepts ARM allocated buffers
-through the newer API.

-From: Dave Stevenson <dave.stevenson@raspberrypi.org>
-Date: Wed, 27 Mar 2019 17:45:01 +0000
-Subject: [PATCH 599/703] drm: vc4: Add an overlay plane to vc4-firmware-kms
-
-This uses a new API that is exposed via the mailbox service
-to stick an element straight on the screen using DispmanX.
-
-The primary and cursor planes have also been switched to using
-the new plane API, and it supports layering based on the DRM
-zpos parameter.

-Subject: [PATCH 601/703] drm: vc4: Add support for multiple displays to fkms
-
-There is a slightly nasty hack in that all crtcs share the
-same SMI interrupt from the firmware. This seems to currently
-work well enough, but ought to be fixed at a later date.

+vblank needs to be enabled and disabled by the driver to avoid the

+vc4_fkms_disable_vblank needs to signal that we don't want vblank

- function
-
-"32a3dbe drm/vc4: Nuke preclose hook" removed vc4_cancel_page_flip,
-but vc4_fkms_cancel_page_flip was still be added to with the
-fkms driver, even though it was never called.
-Nuke it too.

+Subject: [PATCH 612/725] drm/v3d: Add support for compute shader dispatch.
+
+The compute shader dispatch interface is pretty simple -- just pass in
+the regs that userspace has passed us, with no CLs to run.  However,
+with no CL to run it means that we need to do manual cache flushing of
+the L2 after the HW execution completes (for SSBO, atomic, and
+image_load_store writes that are the output of compute shaders).
+
+This doesn't yet expose the L2 cache's ability to have a region of the
+address space not write back to memory (which could be used for
+shared_var storage).
+
+So far, the Mesa side has been tested on V3D v4.2 simpenrose (passing
+the ES31 tests), and on the kernel side on 7278 (failing atomic
+compswap tests in a way that doesn't reproduce on simpenrose).
+
+v2: Fix excessive allocation for the clean_job (reported by Dan
+    Carpenter).  Keep refs on jobs until clean_job is finished, to
+    avoid spurious MMU errors if the output BOs are freed by userspace
+    before L2 cleaning is finished.

-Subject: [PATCH 616/703] drm/v3d: Add support for compute shader dispatch.
-
-The compute shader dispatch interface is pretty simple -- just pass in
-the regs that userspace has passed us, with no CLs to run.  However,
-with no CL to run it means that we need to do manual cache flushing of
-the L2 after the HW execution completes (for SSBO, atomic, and
-image_load_store writes that are the output of compute shaders).
-
-This doesn't yet expose the L2 cache's ability to have a region of the
-address space not write back to memory (which could be used for
-shared_var storage).
-
-So far, the Mesa side has been tested on V3D v4.2 simpenrose (passing
-the ES31 tests), and on the kernel side on 7278 (failing atomic
-compswap tests in a way that doesn't reproduce on simpenrose).
-
-v2: Fix excessive allocation for the clean_job (reported by Dan
-    Carpenter).  Keep refs on jobs until clean_job is finished, to
-    avoid spurious MMU errors if the output BOs are freed by userspace
-    before L2 cleaning is finished.

+In theory we can add plumbing for setting the DPI/DSI mode from

-The overscan support was required for the old mailbox API

+
+The VPU has configured clocks for 4k (or not) via config.txt,
+and will limit the choice of video modes based on that.
+Make fkms query it for these limits too to avoid selecting modes
+that can not be handled by the current clock setup.

-Subject: [PATCH 623/703] drm: vc4: handle the case where there are no
- available displays
-
-It's reasonable for the firmware to return zero as the number of
-attached displays. Handle this case as otherwise drm thinks that
-the DSI panel is attached, which is nonsense.

+ being Pi4
+
+The max resolution had been increased from 2048 to 7680 for all
+platforms. This code is common with Pi0-3 which have a max render
+target for GL of 2048, therefore the increased resolution has to
+be conditional on the platform.
+Switch based on whether the bcm2835-v3d node is found, as that is
+not present on Pi4. (There is a potential configuration on Pi0-3
+with no v3d, but this is very unlikely).

-From: Dave Stevenson <dave.stevenson@raspberrypi.org>
-Date: Thu, 30 May 2019 13:56:15 +0100
-Subject: [PATCH 627/703] drm/vc4: fkms to query the VPU for HDMI clock limits
-
-The VPU has configured clocks for 4k (or not) via config.txt,
-and will limit the choice of video modes based on that.
-Make fkms query it for these limits too to avoid selecting modes
-that can not be handled by the current clock setup.

-Subject: [PATCH 628/703] drm/vc4: Max resolution of 7680 is conditional on
- being Pi4
-
-The max resolution had been increased from 2048 to 7680 for all
-platforms. This code is common with Pi0-3 which have a max render
-target for GL of 2048, therefore the increased resolution has to
-be conditional on the platform.
-Switch based on whether the bcm2835-v3d node is found, as that is
-not present on Pi4. (There is a potential configuration on Pi0-3
-with no v3d, but this is very unlikely).

+Subject: [PATCH 628/725] staging: vc-sm-cma: Add in userspace allocation API
+
+Replacing the functionality from the older vc-sm driver,
+add in a userspace API that allows allocation of buffers,
+and importing of dma-bufs.
+The driver hands out dma-buf fds, therefore much of the
+handling around lifespan and odd mmaps from the old driver
+goes away.

-  * and taking some code for CMA/dmabuf handling from the Android Ion
-  * driver (Google/Linaro).
-  *
-- * This is cut down version to only support import of dma_bufs from
-- * other kernel drivers. A more complete implementation of the old
-- * vmcs_sm functionality can follow later.
-  *
-+ * This driver has 3 main uses:
-+ * 1) Allocating buffers for the kernel or userspace that can be shared with the
-+ *    VPU.
-+ * 2) Importing dmabufs from elsewhere for sharing with the VPU.
-+ * 3) Allocating buffers for use by the VPU.
-+ *
-+ * In the first and second cases the native handle is a dmabuf. Releasing the
-+ * resource inherently comes from releasing the dmabuf, and this will trigger
-+ * unmapping on the VPU. The underlying allocation and our buffer structure are
-+ * retained until the VPU has confirmed that it has finished with it.
-+ *
-+ * For the VPU allocations the VPU is responsible for triggering the release,
-+ * and therefore the released message decrements the dma_buf refcount (with the
-+ * VPU mapping having already been marked as released).

-Subject: [PATCH 632/703] staging: vc-sm-cma: Add in userspace allocation API
-
-Replacing the functionality from the older vc-sm driver,
-add in a userspace API that allows allocation of buffers,
-and importing of dma-bufs.
-The driver hands out dma-buf fds, therefore much of the
-handling around lifespan and odd mmaps from the old driver
-goes away.

+Subject: [PATCH 632/725] staging: vcsm-cma: Fixup the alloc code handling of
+ kernel_id
+
+The allocation code had been copied in from an old branch prior
+to having added the IDR for 64bit support. It was therefore pushing
+a pointer into the kernel_id field instead of an IDR handle, the
+lookup therefore failed, and we never released the buffer.

-Subject: [PATCH 636/703] staging: vcsm-cma: Fixup the alloc code handling of
- kernel_id
-
-The allocation code had been copied in from an old branch prior
-to having added the IDR for 64bit support. It was therefore pushing
-a pointer into the kernel_id field instead of an IDR handle, the
-lookup therefore failed, and we never released the buffer.

+Subject: [PATCH 638/725] overlays: Add the spi-gpio40-45 overlay
+
+The 2711 B0 boot EEPROM is programmed via SPI0 on GPIO
+pins 40-43 CS0. Add a device tree overlay to optionally
+change the SPI0 pinmux from the external GPIO pins to
+the boot EEPROM pins.

+Subject: [PATCH 641/725] 2711: Add basic 64-bit support
+
+This commit adds initial support for 64-bit 2711 builds. However,
+it will only work as much as it does if the Pi4 RAM is limited to
+1GB - more than that and several things break (SD card, coherent
+allocations, etc.)

-Subject: [PATCH 645/703] 2711: Add basic 64-bit support
-
-This commit adds initial support for 64-bit 2711 builds. However,
-it will only work as much as it does if the Pi4 RAM is limited to
-1GB - more than that and several things break (SD card, coherent
-allocations, etc.)

+Subject: [PATCH 645/725] arm: dts: Change downstream vchiq compatible string
+
+The new cache line size mechanism requires a different vchiq compatible
+string on BCM2836 and BCM2837, but the downstream dts files didn't
+inherit the upstream changes.

-Subject: [PATCH 650/703] bcm2835-dma: Add proper 40-bit DMA support
-
-The 40-bit additions are not fully tested, but it should be
-capable of supporting both 40-bit memcpy on BCM2711 and regular
-Lite channels on BCM2835.

+Subject: [PATCH 656/725] usb: add plumbing for updating interrupt endpoint
+ interval state
+
+xHCI caches device and endpoint data after the interface is configured,
+so an explicit command needs to be issued for any device driver wanting
+to alter the polling interval of an endpoint.
+
+Add usb_fixup_endpoint() to allow drivers to do this. The fixup must be
+called after calculating endpoint bandwidth requirements but before any
+URBs are submitted.
+
+If polling intervals are shortened, any bandwidth reservations are no
+longer valid but in practice polling intervals are only ever relaxed.
+
+Limit the scope to interrupt transfers for now.

+Subject: [PATCH 659/725] drm: vc4: Add status of which display is updated
+ through vblank
+
+Previously multiple  displays were slaved off the same SMI
+interrupt, triggered by HVS channel 1 (HDMI0).
+This doesn't work if you only have a DPI or DSI screen (HVS channel
+0), and gives slightly erroneous results with dual HDMI as the
+events for HDMI1 are incorrect.
+
+Use SMIDSW0 and SMIDSW1 registers to denote which display has
+triggered the vblank.
+Handling should be backwards compatible with older firmware.

-Subject: [PATCH 660/703] usb: add plumbing for updating interrupt endpoint
- interval state
-
-xHCI caches device and endpoint data after the interface is configured,
-so an explicit command needs to be issued for any device driver wanting
-to alter the polling interval of an endpoint.
-
-Add usb_fixup_endpoint() to allow drivers to do this. The fixup must be
-called after calculating endpoint bandwidth requirements but before any
-URBs are submitted.
-
-If polling intervals are shortened, any bandwidth reservations are no
-longer valid but in practice polling intervals are only ever relaxed.
-
-Limit the scope to interrupt transfers for now.

-Subject: [PATCH 663/703] drm: vc4: Add status of which display is updated
- through vblank
-
-Previously multiple  displays were slaved off the same SMI
-interrupt, triggered by HVS channel 1 (HDMI0).
-This doesn't work if you only have a DPI or DSI screen (HVS channel
-0), and gives slightly erroneous results with dual HDMI as the
-events for HDMI1 are incorrect.
-
-Use SMIDSW0 and SMIDSW1 registers to denote which display has
-triggered the vblank.
-Handling should be backwards compatible with older firmware.

+vchiq on Pi4 is no longer under the soc node, therefore it

+Switch to using the configuration of the old dma controller as

-doesn't get the dma-ranges for the VPU.
-
-Switch to using the configuration of the old dma controller as
-that will set the dma-ranges correctly.

+
+Kernels since 4.19 have required the correct manufacture name in the
+compatible string for I2C devices, and unfortunately the one for the
+Dallas/Maxim DS1307 should have been "dallas,ds1307" and not
+"maxim,ds1307".

-
-1) The top-level .dts files now include parallel chains of bcm27xx.dtsi
-   and bcm27xx-rpi.dtsi files, with no cross-inclusion between the two
-   chains.
-
-2) Move definitions and deletions to the point of maximum commonality
-   to reduce redundancy.

+
+commit 0e3743d870711ae4daf1e7170c8d9381564e244d upstream.
+
+The ds2805 has a structure named: w1_family_2d, which surely
+comes from a w1_ds2431 module. This commit fixes this name to
+prevent confusion and mark a correct family name.

-Kernels since 4.19 have required the correct manufacture name in the

-Dallas/Maxim DS1307 should have been "dallas,ds1307" and not

+
+commit c50d09a86172073f55ebac0b92ad5a75907d64e7 upstream.
+
+The state_read() was calling PIO_ACCESS_READ once and bail out if it
+failed for this first time.
+This commit is improving this to trying more times before it give up,
+similarly as the write call is currently doing.

+Subject: [PATCH 674/725] w1: ds2413: when the slave is not responding during
+ read, select it again
+
+commit 3856032a0628e6b94badb9131a706dda185e071d upstream.
+
+The protocol is not allowing to obtain a byte of 0xff for PIO_ACCESS_READ
+call. It is very likely that the slave was not addressed properly and
+it is just not respoding (leaving the bus in logic high state) during
+the read of sampled PIO value.
+We cannot just call w1_reset_resume_command() because the problem will
+persist, instead try selecting (addressing) the slave again.

-
-commit c50d09a86172073f55ebac0b92ad5a75907d64e7 upstream.
-
-The state_read() was calling PIO_ACCESS_READ once and bail out if it
-failed for this first time.
-This commit is improving this to trying more times before it give up,
-similarly as the write call is currently doing.

-Subject: [PATCH 678/703] w1: ds2413: when the slave is not responding during
- read, select it again
-
-commit 3856032a0628e6b94badb9131a706dda185e071d upstream.
-
-The protocol is not allowing to obtain a byte of 0xff for PIO_ACCESS_READ
-call. It is very likely that the slave was not addressed properly and
-it is just not respoding (leaving the bus in logic high state) during
-the read of sampled PIO value.
-We cannot just call w1_reset_resume_command() because the problem will
-persist, instead try selecting (addressing) the slave again.

+Downstream Raspberry Pi dts files add "coherent_pool=1M" to the kernel

+uses a new XCHI interface instead. UAS also benefits from a larger
+coherent_pool value, so replicate the addition in bcm2711-rpi-4-b.dts.

-Subject: [PATCH 685/703] arm: dts: Add coherent_pool=1M to Pi 4 bootargs
-
-Downstream Raspberry Pi dts files add "coherent_pool=1M" to the kernel
-command line to aid the dwc_otg driver, but this excluded Pi 4 which
-uses a new XCHI interface instead. UAS also benefits from a larger
-coherent_pool value, so replicate the addition in bcm2711-rpi-4-b.dts.

+Subject: [PATCH 685/725] overlays: Correct gpio-fan gpio flags for 4.19
+
+The gpio-fan overlay was submitted for the 4.14 kernel where the second
+value in the Device Tree gpios declaration was ignored (thanks to an
+old-style driver), allowing the fan-control output to be active-high
+even though the declaration appears to request it be active-low.
+The gpio-fan driver in 4.19 uses GPIO descriptors and honours the
+active-low flag that the overlay (accidentally?) supplies.
+
+Change/correct the flags field to mark the GPIO as active-high.

+Subject: [PATCH 686/725] staging: vcsm-cma: Remove cache manipulation ioctl
+ from ARM64
+
+The cache flushing ioctls are used by the Pi3 HEVC hw-assisted
+decoder as it needs finer grained flushing control than dma_ops
+allow.
+These cache calls are not present for ARM64, therefore disable
+them. We are not actively supporting 64bit kernels at present,
+and the use case of the HEVC decoder is fairly limited.

+Rework to use dma_alloc_coherent instead of the CMA

-Subject: [PATCH 689/703] overlays: Correct gpio-fan gpio flags for 4.19
-
-The gpio-fan overlay was submitted for the 4.14 kernel where the second
-value in the Device Tree gpios declaration was ignored (thanks to an
-old-style driver), allowing the fan-control output to be active-high
-even though the declaration appears to request it be active-low.
-The gpio-fan driver in 4.19 uses GPIO descriptors and honours the
-active-low flag that the overlay (accidentally?) supplies.
-
-Change/correct the flags field to mark the GPIO as active-high.

- from ARM64
-
-The cache flushing ioctls are used by the Pi3 HEVC hw-assisted
-decoder as it needs finer grained flushing control than dma_ops
-allow.
-These cache calls are not present for ARM64, therefore disable
-them. We are not actively supporting 64bit kernels at present,
-and the use case of the HEVC decoder is fairly limited.

+
+Upstream commit e5079cf11373e4cc98be8b1072aece429eb2d4d2.
+
+Set the capabilities field of v4l2_requestbuffers and v4l2_create_buffers.
+
+The various mapping modes were easy, but for signaling the request capability
+a new 'supports_requests' bitfield was added to videobuf2-core.h (and set in
+vim2m and vivid). Drivers have to set this bitfield for any queue where
+requests are supported.

+Subject: [PATCH 695/725] media: vb2: Allow reqbufs(0) with "in use" MMAP
+ buffers
+
+Upstream commit d644cca50f366cd109845ae92e37c09ed79adf81
+
+Videobuf2 presently does not allow VIDIOC_REQBUFS to destroy outstanding
+buffers if the queue is of type V4L2_MEMORY_MMAP, and if the buffers are
+considered "in use".  This is different behavior than for other memory
+types and prevents us from deallocating buffers in following two cases:
+
+1) There are outstanding mmap()ed views on the buffer. However even if
+   we put the buffer in reqbufs(0), there will be remaining references,
+   due to vma .open/close() adjusting vb2 buffer refcount appropriately.
+   This means that the buffer will be in fact freed only when the last
+   mmap()ed view is unmapped.
+
+2) Buffer has been exported as a DMABUF. Refcount of the vb2 buffer
+   is managed properly by VB2 DMABUF ops, i.e. incremented on DMABUF
+   get and decremented on DMABUF release. This means that the buffer
+   will be alive until all importers release it.
+
+Considering both cases above, there does not seem to be any need to
+prevent reqbufs(0) operation, because buffer lifetime is already
+properly managed by both mmap() and DMABUF code paths. Let's remove it
+and allow userspace freeing the queue (and potentially allocating a new
+one) even though old buffers might be still in processing.
+
+To let userspace know that the kernel now supports orphaning buffers
+that are still in use, add a new V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS
+to be set by reqbufs and create_bufs.
+
+[p.zabel@pengutronix.de: added V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS,
+ updated documentation, and added back debug message]

+Subject: [PATCH 696/725] overlays: Add real parameters to the rpi-poe overlay
+
+As a result of being loaded by the POE HAT EEPROM, the rpi-poe overlay
+doesn't expose parameters in the usual way; instead it adds them to
+the base Device Tree, and the user is expected to use "dtparam=..."
+to access them.
+
+To make the documentation correct and to protect users who load the
+overlay explicitly, expecting to be able to use the parameters, add
+real parameters to the overlay as well.

+retained for backwards compatibility as files that just include
+the new versions - the README marks them as being deprecated.

+Subject: [PATCH 698/725] i2c: bcm2835: Move IRQ request after clock code in
+ probe
+
+Commit 4a5cfa39465cad25dd736d7ceba8a5d32eea4ecc upstream.
+
+If any of the clock code in the probe fails and returns, the IRQ
+will not be freed.  Moving the IRQ request to last allows it to
+be freed on any errors further up in the probe function.  devm_
+calls can apparently not be used because there are some potential
+race conditions that will arise.

-Subject: [PATCH 698/703] media: vb2: set reqbufs/create_bufs capabilities
-
-Upstream commit e5079cf11373e4cc98be8b1072aece429eb2d4d2.
-
-Set the capabilities field of v4l2_requestbuffers and v4l2_create_buffers.
-
-The various mapping modes were easy, but for signaling the request capability
-a new 'supports_requests' bitfield was added to videobuf2-core.h (and set in
-vim2m and vivid). Drivers have to set this bitfield for any queue where
-requests are supported.

+Subject: [PATCH 699/725] i2c: bcm2835: Ensure clock exists when probing
+
+Commit 9de93b04df16b055824e3f1f13fedb90fbcf2e4f upstream.
+
+Probe function fails to recognize that upstream clock actually
+doesn't yet exist because clock driver has not been initialized.
+Actually try to go get the clock and test for its existence
+before trying to set up a downstream clock based upon it.
+
+This fixes a bug that causes the i2c driver not to work with
+monolithic kernels.

-Subject: [PATCH 699/703] media: vb2: Allow reqbufs(0) with "in use" MMAP
- buffers
-
-Upstream commit d644cca50f366cd109845ae92e37c09ed79adf81
-
-Videobuf2 presently does not allow VIDIOC_REQBUFS to destroy outstanding
-buffers if the queue is of type V4L2_MEMORY_MMAP, and if the buffers are
-considered "in use".  This is different behavior than for other memory
-types and prevents us from deallocating buffers in following two cases:
-
-1) There are outstanding mmap()ed views on the buffer. However even if
-   we put the buffer in reqbufs(0), there will be remaining references,
-   due to vma .open/close() adjusting vb2 buffer refcount appropriately.
-   This means that the buffer will be in fact freed only when the last
-   mmap()ed view is unmapped.
-
-2) Buffer has been exported as a DMABUF. Refcount of the vb2 buffer
-   is managed properly by VB2 DMABUF ops, i.e. incremented on DMABUF
-   get and decremented on DMABUF release. This means that the buffer
-   will be alive until all importers release it.
-
-Considering both cases above, there does not seem to be any need to
-prevent reqbufs(0) operation, because buffer lifetime is already
-properly managed by both mmap() and DMABUF code paths. Let's remove it
-and allow userspace freeing the queue (and potentially allocating a new
-one) even though old buffers might be still in processing.
-
-To let userspace know that the kernel now supports orphaning buffers
-that are still in use, add a new V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS
-to be set by reqbufs and create_bufs.
-
-[p.zabel@pengutronix.de: added V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS,
- updated documentation, and added back debug message]

-
-As a result of being loaded by the POE HAT EEPROM, the rpi-poe overlay
-doesn't expose parameters in the usual way; instead it adds them to
-the base Device Tree, and the user is expected to use "dtparam=..."
-to access them.
-
-To make the documentation correct and to protect users who load the

+Subject: [PATCH 700/725] overlays: i2c-gpio: Fix the "bus" parameter
+
+The "bus" parameter has two functions - providing unique names for
+multiple instances of the overlay, and allowing the number of the bus
+(i.e. "i2c-<bus>") to be specified. The second function hasn't worked
+as intended because the overlay doesn't include a "reg" property and
+the firmware intentionally won't create a "reg" property if one doesn't
+already exist.
+
+Allow the bus numbering scheme to work as intended by providing a "reg"
+with a default value that means "the next available one".

+From e70cb8a67901499d75f4ed4d5bd120a1ceace698 Mon Sep 17 00:00:00 2001
+From: Phil Elwell <phil@raspberrypi.org>
+Date: Thu, 11 Jul 2019 13:13:39 +0100
+Subject: [PATCH 701/725] tty: amba-pl011: Make TX optimisation conditional
+
+pl011_tx_chars takes a "from_irq" parameter to reduce the number of
+register accesses. When from_irq is true the function assumes that the
+FIFO is half empty and writes up to half a FIFO's worth of bytes
+without polling the FIFO status register, the reasoning being that
+the function is being called as a result of the TX interrupt being
+raised. This logic would work were it not for the fact that
+pl011_rx_chars, called from pl011_int before pl011_tx_chars, releases
+the spinlock before calling tty_flip_buffer_push.
+
+A user thread writing to the UART claims the spinlock and ultimately
+calls pl011_tx_chars with from_irq set to false. This reverts to the
+older logic that polls the FIFO status register before sending every
+byte. If this happen on an SMP system during the section of the IRQ
+handler where the spinlock has been released, then by the time the TX
+interrupt handler is called, the FIFO may already be full, and any
+further writes are likely to be lost.
+
+The fix involves adding a per-port flag that is true iff running from
+within the interrupt handler and the spinlock has not yet been released.
+This flag is then used as the value for the from_irq parameter of
+pl011_tx_chars, causing polling to be used in the unsafe case.
+
+Fixes: 1e84d22322ce ("serial/amba-pl011: Refactor and simplify TX FIFO handling")

- probe
-
-Commit 4a5cfa39465cad25dd736d7ceba8a5d32eea4ecc upstream.
-
-If any of the clock code in the probe fails and returns, the IRQ
-will not be freed.  Moving the IRQ request to last allows it to
-be freed on any errors further up in the probe function.  devm_
-calls can apparently not be used because there are some potential
-race conditions that will arise.

+Subject: [PATCH 702/725] xhci: add quirk for host controllers that don't
+ update endpoint DCS
+
+Seen on a VLI VL805 PCIe to USB controller. For non-stream endpoints
+at least, if the xHC halts on a particular TRB due to an error then
+the DCS field in the Out Endpoint Context maintained by the hardware
+is not updated with the current cycle state.
+
+Using the quirk XHCI_EP_CTX_BROKEN_DCS and instead fetch the DCS bit
+from the TRB that the xHC stopped on.

-
-Commit 9de93b04df16b055824e3f1f13fedb90fbcf2e4f upstream.
-
-Probe function fails to recognize that upstream clock actually
-doesn't yet exist because clock driver has not been initialized.
-Actually try to go get the clock and test for its existence
-before trying to set up a downstream clock based upon it.
-
-This fixes a bug that causes the i2c driver not to work with
-monolithic kernels.

+
+The BCM2835 I2C blocks have a register to set the clock-stretch
+timeout - how long the device is allowed to hold SCL low - in bus
+cycles. The current driver doesn't write to the register, therefore
+the default value of 64 cycles is being used for all devices.
+
+Set the timeout to the value recommended for SMBus - 35ms.

+Subject: [PATCH 706/725] configs: arm64/bcm2711: Use CONFIG_BRCMSTB_THERMAL
+ instead of CONFIG_BCM2835_THERMAL
+
+The Raspberry Pi 4 uses the brcmstb thermal driver rather than brcm2835,
+based on the device tree compatible string 'brcm,avs-tmon-bcm2838'. With
+CONFIG_BRCMSTB_THERMAL enabled, reading temperature from
+/sys/class/thermal/thermal_zone0/temp works as expected instead of
+returning EINVAL.

+Subject: [PATCH 707/725] overlays: dpi18 and dpi24 vc4 compatibility
+
+The dpi overlays use the fb device tree node as a place to hang the
+necessary pinctrl changes. With one of the VC4 overlays loaded, the
+fb node is disabled so the changes have no effect.
+
+Modify the overlays to also use the vc4 node, to cover both use
+cases.

+Subject: [PATCH 708/725] overlays: Add i2c0 and i2c1 for regularity
+
+The new i2c overlays for pi4 (i2c3, i2c4, i2c5, i2c6) have a
+standardised interface that allows pin groups to be chosen
+atomically rather than as individual pins. Add i2c0 and i2c1
+overlays to fit the naming scheme and parameter usage, deprecating
+i2c0-bcm2708 and i2c1-bcm2708.

+Subject: [PATCH 715/725] overlays: audremap: Support GPIOs 18 & 19
+
+PWM audio can also be used on GPIOs 18 and 19, so add the pins_18_19
+parameter to select that location. pins_12_13 explicitly chooses GPIOs
+12 and 13, although this is the default behaviour so is there only for
+completeness.
+
+See: https://github.com/raspberrypi/firmware/issues/1178

+Subject: [PATCH 718/725] drm/connector: Allow creation of margin props alone
+
+Commit 6c4f52dca36f5e3e2354c30591d38e92f4657ed9 upstream.
+
+TV margins properties can only be added as part of the SDTV TV
+connector properties creation, but we might need those props for HDMI
+TVs too, so let's move the margins props creation in a separate
+function and expose it to drivers.
+
+We also add an helper to attach margins props to a connector.

+Subject: [PATCH 719/725] drm/vc4: Take margin setup into account when updating
+ planes
+
+Commit 666e73587f90f42d90385c1bea1009a650bf73f4 upstream.
+
+Applyin margins is just a matter of scaling all planes appropriately
+and adjusting the CRTC X/Y offset to account for the
+left/right/top/bottom borders.
+
+Create a vc4_plane_margins_adj() function doing that and call it from
+vc4_plane_setup_clipping_and_scaling() so that we are ready to attach
+margins properties to the HDMI connector.

+Subject: [PATCH 720/725] drm/vc4: Attach margin props to the HDMI connector
+
+Commit db999538fdb0679629d90652f8a1437df1e85a7d upstream.
+
+Now that the plane code takes the margins setup into account, we can
+safely attach margin props to the HDMI connector.
+
+We also take care of filling AVI infoframes correctly to expose the
+top/botton/left/right bar.
+
+Note that those margin props match pretty well the
+overscan_{left,right,top,bottom} properties defined in config.txt and
+parsed by the VC4 firmware.

++                                0dB. ie. it can attenuate but not provide

++                                as it will prevent clipping. By appending
++                                the 24dB_digital_gain parameter, the Digital
++                                volume control will allow up to 24dB of
++                                gain. If this parameter is enabled, it is the
++                                responsibility of the user to ensure that
++                                the Digital volume control is set to a value
