Its power stage is capable of supplying a maximum total current of roughly 1500mA. The TPS6131x provides three constant-current sinks, capable of sinking up to 2 × 400mA (LED1 and LED3) and 800mA (LED2) in flash mode. In torch mode each sink (LED1, LED2, LED3) supports currents up to 175m Signed-off-by: Matthias Fend Reviewed-by: Krzysztof Kozlowski --- Changes in v2: - Bindings: Extend device description - Bindings: Drop unused address/size cells - Bindings: Use fallback compatible - Bindings: Corrected minimum current for 50mA steps - Bindings: Drop node label - Fix name of REGISTER4 INDC shift define - Save device instead i2c_client in private data - Add comment for mutex - Use macro to convert from uA to mA - Use defines to describe initial register values - Add safety delay during reset sequence - Use fixed value enum to set the mode - Renamed some local variables - Re-sorted local variables - Replaced ifdefs for V4L2_FLASH_LED_CLASS - Improved some error messages - Link to v1: https://lore.kernel.org/r/20250228-leds-tps6131x-v1-0-d1071d90f9ea@emfend.at --- Matthias Fend (2): dt-bindings: leds: add Texas Instruments TPS6131x flash LED driver leds: tps6131x: add support for Texas Instruments TPS6131X flash LED driver .../devicetree/bindings/leds/ti,tps61310.yaml | 120 ++++ MAINTAINERS | 7 + drivers/leds/flash/Kconfig | 11 + drivers/leds/flash/Makefile | 1 + drivers/leds/flash/leds-tps6131x.c | 794 +++++++++++++++++++++ 5 files changed, 933 insertions(+) --- base-commit: ffd294d346d185b70e28b1a28abe367bbfe53c04 change-id: 20250227-leds-tps6131x-a7437883e400 Best regards,
