Subject: [PATCH 0/5] ChromeOS Embedded Controller LED driver

Add a LED driver that supports the LED devices exposed by the
ChromeOS Embedded Controller.

Patch 1-3 add a utility function to the led subsystem.
Patch 4 introduces the actual driver.
Patch 5 registers the driver through the cros_ec mfd devices.

Currently the driver introduces some non-standard LED functions.
(See "cros_ec_led_functions")

Tested on a Framework 13 AMD, Firmware 3.05.
