+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";
+	pinctrl-0 = <&pmic_int>;
+	reg = <0x1b>;
+	rockchip,system-power-controller;
