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.
