+RK808 Power Management Integrated Circuit
+
+Required properties:
+- compatible: "rockchip,rk808"
+- reg: I2C slave address
+- interrupt-parent: The parent interrupt controller.
+- interrupts: the interrupt outputs of the controller.
+- pinctrl-names: Should contain only one value - "default".
+- pinctrl-0: Should specify pin control groups used for this controller.
+- regulators: This is the list of child nodes that specify the regulator
+ initialization data for defined regulators. Not all regulators for the given
+ device need to be present. The definition for each of these nodes is defined
+ using the standard binding for regulators found at
+ Documentation/devicetree/bindings/regulator/regulator.txt.
+
+Optional properties:
+- rockchip,system-power-controller: Telling whether or not this pmic is controlling
+ the system power.
+
+Example:
+rk808: pmic@1b {
+ compatible = "rockchip,rk808";
+ interrupt-parent = <&gpio0>;
+ interrupts = <4 IRQ_TYPE_EDGE_FALLING>;
+ pinctrl-names = "default";
