The implementation is based on information extracted from downstream as the datasheet provided by a distributor of the hardware didn't include any information about the i2c register description. Signed-off-by: André Apitzsch --- Changes in v3: - Add R-b tag to first patch - Extend driver commit message - Improve readability of defines by using BIT() - Rename some variables/parameters * led_no -> led_id * level -> brightness * curr -> fled_{strobe,torch}_used_tmp * mask -> {flash,torch}_mask * i -> child_num - Restructure structs ("Place th big stuff at the top") - Declare 'child' on a separate line - Move multi-line assignments out of declaration block - Update warning/error messages and comments - Use gotos to handle error path - Use devm API to cleanup module's resources - Init mutex before LED class device is registered to avoid race condition - Link to v2: https://lore.kernel.org/r/20240401-sy7802-v2-0-1138190a7448@apitzsch.eu Changes in v2: - bindings: remove unneeded allOf - bindings: example: move flash-led-controller under i2c node to fix check error - Cc to phone-devel - Link to v1: https://lore.kernel.org/r/20240327-sy7802-v1-0-db74ab32faaf@apitzsch.eu --- André Apitzsch (3): dt-bindings: leds: Add Silergy SY7802 flash LED leds: sy7802: Add support for Silergy SY7802 flash LED controller arm64: dts: qcom: msm8939-longcheer-l9100: Add rear flash .../devicetree/bindings/leds/silergy,sy7802.yaml | 100 ++++ .../boot/dts/qcom/msm8939-longcheer-l9100.dts | 26 + drivers/leds/flash/Kconfig | 11 + drivers/leds/flash/Makefile | 1 + drivers/leds/flash/leds-sy7802.c | 546 +++++++++++++++++++++ 5 files changed, 684 insertions(+) --- base-commit: 6a03b35e4395eb2d6e89a38aca00a9fe9cb39ba1 change-id: 20240325-sy7802-f40fc6f56525 Best regards,
