Most of the time Mobile devices come with single physical key for POWER,
which if pressed for less than 500ms (configurable) then it will only
report KEY_END (which say locks the screen on mobile) and if it pressed
more than 500ms then it will also report KEY_POWER event too, which will
say display menu on your mobile for asking you to suspend/switch off/etc, operations.

For the timers I can move from hrtimers to regular timers.

For the header file, I can move them to include/linux/mfd too. No problem on that.
