8 bool "Enable Driver Model for Misc drivers"
11 Enable driver model for miscellaneous devices. This class is
12 used only for those do not fit other more general classes. A
13 set of generic read, write and ioctl methods may be used to
17 bool "Altera Sysid support"
20 Select this to enable a sysid for Altera devices. Please find
21 details on the "Embedded Peripherals IP User Guide" of Altera.
24 bool "Enable crosec command"
27 Enable command-line access to the Chrome OS EC (Embedded
28 Controller). This provides the 'crosec' command which has
29 a number of sub-commands for performing EC tasks such as
30 updating its flash, accessing a small saved context area
31 and talking to the I2C bus behind the EC (if there is one).
34 bool "Enable Chrome OS EC"
36 Enable access to the Chrome OS EC. This is a separate
37 microcontroller typically available on a SPI bus on Chromebooks. It
38 provides access to the keyboard, some internal storage and may
39 control access to the battery and main PMIC depending on the
40 device. You can use the 'crosec' command to access it.
43 bool "Enable Chrome OS EC I2C driver"
46 Enable I2C access to the Chrome OS EC. This is used on older
47 ARM Chromebooks such as snow and spring before the standard bus
48 changed to SPI. The EC will accept commands across the I2C using
49 a special message protocol, and provide responses.
52 bool "Enable Chrome OS EC LPC driver"
55 Enable I2C access to the Chrome OS EC. This is used on x86
56 Chromebooks such as link and falco. The keyboard is provided
57 through a legacy port interface, so on x86 machines the main
58 function of the EC is power and thermal management.
60 config CROS_EC_SANDBOX
61 bool "Enable Chrome OS EC sandbox driver"
62 depends on CROS_EC && SANDBOX
64 Enable a sandbox emulation of the Chrome OS EC. This supports
65 keyboard (use the -l flag to enable the LCD), verified boot context,
66 EC flash read/write/erase support and a few other things. It is
67 enough to perform a Chrome OS verified boot on sandbox.
70 bool "Enable Chrome OS EC SPI driver"
73 Enable SPI access to the Chrome OS EC. This is used on newer
74 ARM Chromebooks such as pit, pi and nyan-big. The SPI interface
75 provides a faster and more robust interface than I2C but the bugs
79 bool "Enable FSL SEC_MON Driver"
81 Freescale Security Monitor block is responsible for monitoring
83 Security Monitor can be transitioned on any security failures,
84 like software violations or hardware security violations.
87 bool "Enable MXC OCOTP Driver"
89 If you say Y here, you will get support for the One Time
90 Programmable memory pages that are stored on the some
91 Freescale i.MX processors.
93 config NUVOTON_NCT6102D
94 bool "Enable Nuvoton NCT6102D Super I/O driver"
96 If you say Y here, you will get support for the Nuvoton
97 NCT6102D Super I/O driver. This can be used to enable or
98 disable the legacy UART, the watchdog or other devices
99 in the Nuvoton Super IO chips on X86 platforms.
102 bool "Enable power-sequencing drivers"
105 Power-sequencing drivers provide support for controlling power for
106 devices. They are typically referenced by a phandle from another
107 device. When the device is started up, its power sequence can be
111 bool "Enable power-sequencing drivers for SPL"
114 Power-sequencing drivers provide support for controlling power for
115 devices. They are typically referenced by a phandle from another
116 device. When the device is started up, its power sequence can be
120 bool "Enable PCA9551 LED driver"
122 Enable driver for PCA9551 LED controller. This controller
123 is connected via I2C. So I2C needs to be enabled.
125 config PCA9551_I2C_ADDR
126 hex "I2C address of PCA9551 LED controller"
127 depends on PCA9551_LED
130 The I2C address of the PCA9551 LED controller.
133 bool "Enable support for the Tegra CAR driver"
134 depends on TEGRA_NO_BPMP
136 The Tegra CAR (Clock and Reset Controller) is a HW module that
137 controls almost all clocks and resets in a Tegra SoC.
140 bool "Enable support for the Tegra186 BPMP driver"
143 The Tegra BPMP (Boot and Power Management Processor) is a separate
144 auxiliary CPU embedded into Tegra to perform power management work,
145 and controls related features such as clocks, resets, power domains,
146 PMIC I2C bus, etc. This driver provides the core low-level
147 communication path by which feature-specific drivers (such as clock)
148 can make requests to the BPMP. This driver is similar to an MFD
149 driver in the Linux kernel.
151 config WINBOND_W83627
152 bool "Enable Winbond Super I/O driver"
154 If you say Y here, you will get support for the Winbond
155 W83627 Super I/O driver. This can be used to enable the
156 legacy UART or other devices in the Winbond Super IO chips
162 Hidden option to enable QEMU fw_cfg interface. This will be selected by
163 either CONFIG_CMD_QFW or CONFIG_GENERATE_ACPI_TABLE.
166 bool "Enable driver for generic I2C-attached EEPROMs"
169 Enable a generic driver for EEPROMs attached via I2C.
