Subject[PATCH 0/3] led: ledtrig-transient: add support for hrtimer

These patch series add the LED_BRIGHTNESS_FAST flag support for
ledtrig-transient to use hrtimer so that platforms with high-resolution timer
support can have better accuracy in the trigger duration timing. The need for
this support is driven by the fact that Android has removed the timed_ouput [1]
and is now using led-trigger for handling vibrator control which requires the
timer to be accurate up to a millisecond. However, this flag support would also
allow hrtimer to co-exist with the ktimer without causing warning to the
existing drivers [2].



David Lin (3):
leds: Replace flags bit shift with BIT() macros
leds: Add the LED_BRIGHTNESS_FAST flag
led: ledtrig-transient: add support for hrtimer
