Hi Nicolas, We have LED flash class framework since 2015. Please refer to the following files: Documentation/leds/leds-class-flash.rst Documentation/ABI/testing/sysfs-class-led-flash Documentation/devicetree/bindings/leds/common.yaml drivers/leds/led-class-flash.c Thare are also few LED flash drivers in the tree. Since there seems to be boost feature present on the the device then you might want to compare drivers/leds/leds-max77693.c with its bindings Documentation/devicetree/bindings/mfd/max77693.txt (refer to LED part). Please also remember to include DT bindings patch to your series. On 11/6/20 5:58 PM, Nícolas F. R. A. Prado wrote:
