Thomas Weißschuh June 13, 2024, 2:48 p.m. UTC
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

Applied and submitted for testing.

All being well, I'll follow-up with a cross-subsystem pull-request shortly

Thanks!

I'm not sure which effect this application has on the review comments
you gave to patch 4 (thanks for those, too).

After implementing your requests, should I
* resubmit the whole series
* resubmit only patch 4
* send an incremental patch on top of the series
?
