first DC is in use, yet the DC's DT node is enabled:

(This happens on at least Harmony, Ventana, and likely any other Tegra20
board with display enabled other than Seaboard).

The Tegra DC's DT node represents a display controller. It may itself
drive an integrated RGB display output, or be used by some other display
controller such as HDMI. For this reason the DC node itself is not
enabled/disabled in DT; the DC itself is considered a shared resource, not
the final (board-specific) display output. The node should instantiate a
display output driver only if the rgb subnode is enabled. Other output
drivers are free to use the DC if they are enabled and their DT node
references the DC's DT node. Adapt the Tegra display drivers' bind()
routine to only bind to the DC's DT node if the RGB subnode is enabled.

Now that the display driver does the right thing, remove the workaround

8 years agobuildman: allow more incremental building
Stephen Warren [Mon, 11 Apr 2016 16:48:44 +0000 (10:48 -0600)]
buildman: allow more incremental building

One use-case for buildman is to continually run it interactively after
each small step in a large refactoring operation. This gives more
immediate feedback than making a number of commits and then going back and
testing them. For this to work well, buildman needs to be extremely fast.
At present, a couple issues prevent it being as fast as it could be:

1) Each time buildman runs "make %_defconfig", it runs "make mrproper"
first. This throws away all previous build results, requiring a
from-scratch build. Optionally avoiding this would speed up the build, at
the cost of potentially causing or missing some build issues.

2) A build tree is created per thread rather than per board. When a thread
switches between building different boards, this often causes many files
to be rebuilt due to changing config options. Using a separate build tree
for each board would avoid this. This does put more strain on the system's
disk cache, but it is worth it on my system at least.

This commit adds two command-line options to implement the changes
described above; -I ("--incremental") turns of "make mrproper" and -P
("--per-board-out-dir") creats a build directory per board rather than per
thread.

Tested:

    ./tools/buildman/buildman.py tegra
    ./tools/buildman/buildman.py -I -P tegra
    ./tools/buildman/buildman.py -b tegra_dev tegra
    ./tools/buildman/buildman.py -b tegra_dev -I -P tegra

... each once after deleting the buildman result/work directory, and once
"incrementally" after a previous identical invocation.

Introduce a new driver that supports driver model for pca953x.
The pca953x chips are used as I2C I/O expanders.
This driver is designed to support the following chips:
"
4 bits: pca9536, pca9537
8 bits: max7310, max7315, pca6107, pca9534, pca9538, pca9554,

         tca6416
24 bits: tca6424
40 bits: pca9505, pca9698
"
But for now this driver only supports max 24 bits and pca953x compatible
chips. pca957x compatible chips are not supported now.
These can be addressed when we need to add such support for the different
chips.
This driver has been tested on i.MX6 SoloX Sabreauto board with max7310

=>gpio status -a
Bank gpio@30_:

properly, but instead still containing the timer init values from
the boot ROM which cause timers to expire in 1/4th the time

timer_init is typically not called until board_init_r, however on
am33xx/am43xx udelay is required in sdram_init which is called
from board_init_f, so a call to timer_init is required earlier.

pci: tegra: fix DM conversion issues on Tegra20

Tegra20's PCIe controller has a couple of quirks. There are workarounds in
the driver for these, but they don't work after the DM conversion:

1) The PCI_CLASS value is wrong in HW.

This is worked around in pci_tegra_read_config() by patching up the value
read from that register. Pre-DM, the PCIe core always read this via a
16-bit access to the 16-bit offset 0xa. With DM, 32-bit accesses are used,
so we need to check for offset 0x8 instead. Mask the offset value back to
32-bit alignment to make this work in all cases.

2) Accessing devices other than dev 1 causes a data abort.

Pre-DM, this was worked around in pci_skip_dev(), which the PCIe core code
called during enumeration while iterating over a bus. The DM PCIe core
doesn't use this function. Instead, enhance tegra_pcie_conf_address() to
validate the bdf being accessed, and refuse to access invalid devices.
Since pci_skip_dev() isn't used, delete it.

I've also validated that both these WARs are only needed for Tegra20, by
testing on Tegra30/Cardhu and Tegra124/Jetson TKx. So, compile them in
conditionally.

do this, kernel configuring just the frequency using the default boot
loader configured voltage can fail on many corner lot units.

ARM: OMAP5/DRA7: Move ABB TXDONE mask to voltage structure

ABB TX_DONE mask will vary depending on ABB module. For example,
3630 never had ABB on IVA domain, while OMAP5 does use ABB on MM domain,
DRA7 has it on all domains with the exception of CORE, RTC.

Hence, move the txdone mask definition over to structure describing
voltage domain.
