leds: lm355x, lm3642: support camera LED triggers for flash and torch
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. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>
