- Enable driver model for the Chrome OS EC interface. This
- allows the cros_ec SPI driver to operate with CONFIG_DM_SPI
- but otherwise makes few changes. Since cros_ec also supports
- I2C and LPC (which don't support driver model yet), a full
- conversion is not yet possible.
+ 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 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

+config PWRSEQ
+ bool "Enable power-sequencing drivers"
