Subject: [PATCH v3 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.

Changes in v3:
- Set default_trigger explicitly as the LED core doesn't do this anymore
- Only set intensity for first subled by default
- Link to v2: https://lore.kernel.org/r/20240531-cros_ec-led-v2-0-6cc34408b40d@weissschuh.net
Changes in v2:
- Cosmetic cleanups (Tzung-Bi)
- Add trailing comma to MFD cell array
- Rename LEDs and trigger to "chromeos" prefix, to align with kbd
backlight driver
- Don't use type "rgb" anymore, they are only "multicolor"
- Align commit messages and subject to subsystem standards (Lee)
- Rename led_color_name() to led_get_color_name()
- The same for cros_ec_led_color_name()
- Link to v1: https://lore.kernel.org/r/20240520-cros_ec-led-v1-0-4068fc5c051a@weissschuh.net
