# Multifunction miscellaneous devices

menu "Multifunction device drivers"
config MISC
bool "Enable Driver Model for Misc drivers"
depends on DM
help
Enable driver model for miscellaneous devices. This class is
used only for those do not fit other more general classes. A
set of generic read, write and ioctl methods may be used to
access the device.
config ALTERA_SYSID
bool "Altera Sysid support"
depends on MISC
help
Select this to enable a sysid for Altera devices. Please find
details on the "Embedded Peripherals IP User Guide" of Altera.
config CMD_CROS_EC
bool "Enable crosec command"
depends on CROS_EC
help
Enable command-line access to the Chrome OS EC (Embedded
Controller). This provides the 'crosec' command which has
a number of sub-commands for performing EC tasks such as
updating its flash, accessing a small saved context area
and talking to the I2C bus behind the EC (if there is one).
config CROS_EC
bool "Enable Chrome OS EC"
help
Enable access to the Chrome OS EC. This is a separate
microcontroller typically available on a SPI bus on Chromebooks. It
provides access to the keyboard, some internal storage and may
control access to the battery and main PMIC depending on the
device. You can use the 'crosec' command to access it.
config CROS_EC_I2C
bool "Enable Chrome OS EC I2C driver"
depends on CROS_EC
help
Enable I2C access to the Chrome OS EC. This is used on older
ARM Chromebooks such as snow and spring before the standard bus
changed to SPI. The EC will accept commands across the I2C using
a special message protocol, and provide responses.
config CROS_EC_LPC
bool "Enable Chrome OS EC LPC driver"
depends on CROS_EC
help
Enable I2C access to the Chrome OS EC. This is used on x86
Chromebooks such as link and falco. The keyboard is provided
through a legacy port interface, so on x86 machines the main
function of the EC is power and thermal management.
config CROS_EC_SANDBOX
bool "Enable Chrome OS EC sandbox driver"
depends on CROS_EC && SANDBOX
help
Enable a sandbox emulation of the Chrome OS EC. This supports
keyboard (use the -l flag to enable the LCD), verified boot context,
EC flash read/write/erase support and a few other things. It is
enough to perform a Chrome OS verified boot on sandbox.
config CROS_EC_SPI
bool "Enable Chrome OS EC SPI driver"
depends on CROS_EC
help
Enable SPI access to the Chrome OS EC. This is used on newer
ARM Chromebooks such as pit, pi and nyan-big. The SPI interface
provides a faster and more robust interface than I2C but the bugs
are less interesting.
config FSL_SEC_MON
bool "Enable FSL SEC_MON Driver"
help
Freescale Security Monitor block is responsible for monitoring
system states.
Security Monitor can be transitioned on any security failures,
like software violations or hardware security violations.
config PCA9551_LED
bool "Enable PCA9551 LED driver"
help
Enable driver for PCA9551 LED controller. This controller
is connected via I2C. So I2C needs to be enabled.
config PCA9551_I2C_ADDR
hex "I2C address of PCA9551 LED controller"
depends on PCA9551_LED
default 0x60
help
The I2C address of the PCA9551 LED controller.
config RESET
bool "Enable support for reset drivers"
depends on DM
help
Enable reset drivers which can be used to reset the CPU or board.
Each driver can provide a reset method which will be called to
effect a reset. The uclass will try all available drivers when
reset_walk() is called.
