LM355x and LM3642 support flash and torch functionality.
(Camera driver) (LED trigger for camera) (LED driver) Turn on the flash ...> ledtrig_flash_ctrl(true) ...> LM355x or LM3642 brightness ctrl <actual driving here>
Flash/torch LEDs are controlled by other driver using LED camera trigger APIs, ledtrig_flash_ctrl()/ledtrig_torch_ctrl(). Then, actual device control is activated by each LED driver such like LM355x or LM3642.
