+Optional properties:
+	-maxim,charging-current-microamp: Charging current setting.
+			The device supports 50/100/200/400/600/800uA.
+			If this property is unavailable then it will

+	-maxim,charging-voltage-microvolt: Charging Voltage Limit Setting.
+			Device supports 2500000/3000000/3300000/350000uV.
+			Default will be set to 2500mV. The voltage will be roundoff
+			to nearest lower side if other than above is configured.
+	-maxim,output-resister-ohms: Output resistor on Ohm.
+			Device supports 100/1000/3000/6000 Ohms.
