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. Signed-off-by: Thomas Weißschuh --- 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 --- Thomas Weißschuh (5): leds: core: Introduce led_get_color_name() function leds: multicolor: Use led_get_color_name() function leds: core: Unexport led_colors[] array leds: Add ChromeOS EC driver mfd: cros_ec: Register LED subdevice MAINTAINERS | 5 + drivers/leds/Kconfig | 15 ++ drivers/leds/Makefile | 1 + drivers/leds/led-class-multicolor.c | 2 +- drivers/leds/led-core.c | 12 +- drivers/leds/leds-cros_ec.c | 297 ++++++++++++++++++++++++++++++++++++ drivers/leds/leds.h | 1 - drivers/mfd/cros_ec_dev.c | 9 ++ include/linux/leds.h | 10 ++ 9 files changed, 348 insertions(+), 4 deletions(-) --- base-commit: 4a4be1ad3a6efea16c56615f31117590fd881358 change-id: 20240519-cros_ec-led-3efa24e3991e Best regards,
