The maxim,enabel-sleep is not the valid property.
It should be
maxim,device-state-on-disabled-event = <MAX77620_FPS_INACTIVE_STATE_SLEEP>;

You need to say regulator-ramp-delay if register config is same as what 
platform observed.
This is applicable for all places.

GPIO3 is fps-out and hence it can not be done here. Better to do not 
provide any gpio entry.
