From: André Apitzsch <[email protected]> The phone has a Silergy SY7802 flash LED controller.
Reviewed-by: Konrad Dybcio <[email protected]> Signed-off-by: André Apitzsch <[email protected]> --- This series introduces a driver for the Silergy SY7802 charge pump used in the BQ Aquaris M5 and X5 smartphones. 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. --- Changes in v6: - Drop applied patches 1/3 and 2/3 - Move #address-/size-cells to the end - Add R-b tag - Link to v5: https://lore.kernel.org/r/[email protected] Changes in v5: - Fix language in driver description comment - Unwrap function arguments - Remove unnecessary empty lines - Add Acked-by tag to second patch - Link to v4: https://lore.kernel.org/r/[email protected] Changes in v4: - Use for_each_available_child_of_node_scoped() to simplify code - Use dev_err_probe() to be consistent with the other code in sy7802_probe() - Split devm_add_action() into 2 devm_add_action_or_reset() to simplify code and balance regulator_enable() - Link to v3: https://lore.kernel.org/r/[email protected] 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/[email protected] 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/[email protected] --- .../boot/dts/qcom/msm8939-longcheer-l9100.dts | 27 ++++++++++++++++++++++ 1 file changed, 27 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/msm8939-longcheer-l9100.dts b/arch/arm64/boot/dts/qcom/msm8939-longcheer-l9100.dts index e3404c4455cf..b845da4fa23e 100644 --- a/arch/arm64/boot/dts/qcom/msm8939-longcheer-l9100.dts +++ b/arch/arm64/boot/dts/qcom/msm8939-longcheer-l9100.dts @@ -159,6 +159,26 @@ led@2 { }; }; }; + + flash-led-controller@53 { + compatible = "silergy,sy7802"; + reg = <0x53>; + + enable-gpios = <&tlmm 16 GPIO_ACTIVE_HIGH>; + + pinctrl-0 = <&camera_rear_flash_default>; + pinctrl-names = "default"; + + #address-cells = <1>; + #size-cells = <0>; + + led@0 { + reg = <0>; + function = LED_FUNCTION_FLASH; + color = <LED_COLOR_ID_WHITE>; + led-sources = <0>, <1>; + }; + }; }; &blsp_i2c3 { @@ -318,6 +338,13 @@ camera_front_flash_default: camera-front-flash-default-state { bias-disable; }; + camera_rear_flash_default: camera-rear-flash-default-state { + pins = "gpio9", "gpio16", "gpio51"; + function = "gpio"; + drive-strength = <2>; + bias-disable; + }; + gpio_hall_sensor_default: gpio-hall-sensor-default-state { pins = "gpio20"; function = "gpio"; --- base-commit: 0b58e108042b0ed28a71cd7edf5175999955b233 change-id: 20240325-sy7802-f40fc6f56525 Best regards, -- André Apitzsch <[email protected]>
