Subject[PATCH 2/2] regulator: max77620: disable notifier events for FPS rails
Date
Disabling regulator notifier events if regulator is
configured part of flexible power sequencer(FPS),
there is no SW control to enable/disable if regulator
is configured part of FPS, so disabling notifier events
if client driver try to enable/disable FPS rails.
