The gpio led trigger will allow leds to be triggered by gpio events. When we give the led a gpio number, the trigger will request_irq() on that so we don't have to keep polling for gpio state. It's useful for usecases as n810's keypad leds that could be triggered by the gpio event generated when user slides up to show the keypad. We also provide means for userland to tell us what is the desired brightness for that special led when it goes on so userland could use information from ambient light sensors and not set led brightness too high if it's not necessary.
