1Spreadtrum SC2731 PMIC battery charger binding
2
3Required properties:
4 - compatible: Should be "sprd,sc2731-charger".
5 - reg: Address offset of charger register.
6 - phys: Contains a phandle to the USB phy.
7
8Optional Properties:
9- monitored-battery: phandle of battery characteristics devicetree node.
10  The charger uses the following battery properties:
11- charge-term-current-microamp: current for charge termination phase.
12- constant-charge-voltage-max-microvolt: maximum constant input voltage.
13  See Documentation/devicetree/bindings/power/supply/battery.txt

18		compatible = "simple-battery";
19		charge-term-current-microamp = <120000>;
20		constant-charge-voltage-max-microvolt = <4350000>;
21		......
