-Required properties:
---------------------
-- compatible:		Must be "maxim,max77650-charger"
-
-Optional properties:
---------------------
-- input-voltage-min-microvolt:	Minimum CHGIN regulation voltage. Must be one
-				of: 4000000, 4100000, 4200000, 4300000,
-				4400000, 4500000, 4600000, 4700000.
-- input-current-limit-microamp:	CHGIN input current limit (in microamps). Must
