The Tegra CAR (Clock And Reset) module provides control of most clocks and reset signals within the Tegra SoC. This change implements a driver for this module. However, since the module implements multiple kinds of services (clocks, resets, perhaps more), all this driver does is bind various sub-devices, which in turn provide the real services. This driver is essentially an "MFD" (Multi-Function Device) in Linux kernel speak. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>

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).

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.

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.

Enable I2C access to the Chrome OS EC. This is used on x86

through a legacy port interface, so on x86 machines the main

function of the EC is power and thermal management.

Enable a sandbox emulation of the Chrome OS EC. This supports

keyboard (use the -l flag to enable the LCD), verified boot context,

are less interesting.

|
auxiliary CPU embedded into Tegra to perform power management work,

PMIC I2C bus, etc. This driver provides the core low-level

|
driver in the Linux kernel.
