+Spreadtrum SC2731 PMIC battery charger binding
+
+Required properties:
+ - compatible: Should be "sprd,sc2731-charger".
+ - reg: Address offset of charger register.
+ - phys: Contains a phandle to the USB phy.
+
+Optional Properties:
+- monitored-battery: phandle of battery characteristics devicetree node.
+  The charger uses the following battery properties:
+- charge-term-current-microamp: current for charge termination phase.
+- constant-charge-voltage-max-microvolt: maximum constant input voltage.
+  See Documentation/devicetree/bindings/power/supply/battery.txt
+
+Example:
+
+	bat: battery {
+		compatible = "simple-battery";
+		charge-term-current-microamp = <120000>;
+		constant-charge-voltage-max-microvolt = <4350000>;
+		......
+	};
+
+	sc2731_pmic: pmic@0 {
+		compatible = "sprd,sc2731";
+		reg = <0>;
+		spi-max-frequency = <26000000>;
+		interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>;
+		interrupt-controller;
+		#interrupt-cells = <2>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		charger@0 {
+			compatible = "sprd,sc2731-charger";
+			reg = <0x0>;
+			phys = <&ssphy>;
+			monitored-battery = <&bat>;
+		};
