+RK805 Power Management Integrated Circuit
+
+Required properties:
+- compatible: "rockchip,rk805"
+- reg: I2C slave address
+- interrupt-parent: The parent interrupt controller.
+- interrupts: the interrupt outputs of the controller.
+
+Optional properties:
+- rockchip,system-power-controller: Telling whether or not this pmic is controlling
+ the system power.
+- gpio-controller: Specifies that the node is a gpio controller when you attemp to
+ use the OUT1 or OUT2 pin of RK805 by GPIO general interface.
+- #gpio-cells: Should be two. The first cell is the GPIO number and the second cell
+ is used to specify the GPIO polarity.
+- wakeup-source: Flag to indicate this device can wake system (suspend/resume)
+- vcc1-supply: The input supply for RK805_DCDC_REG1
+- vcc2-supply: The input supply for RK805_DCDC_REG2
+- vcc3-supply: The input supply for RK805_DCDC_REG3
+- vcc4-supply: The input supply for RK805_DCDC_REG4
+- vcc5-supply: The input supply for RK805_LDO_REG1, RK805_LDO_REG2
+- vcc6-supply: The input supply for RK805_LDO_REG3
+
+Regulators: All the regulators of RK805 to be instantiated shall be
+listed in a child node named 'regulators'. Each regulator is represented
+by a child node of the 'regulators' node.
+
+ regulator-name {
+ /* standard regulator bindings here */
+ };
+
+Following regulators of the RK805 PMIC block are supported. Note that
+the 'n' in regulator name, as in RK805_DCDC_REGn or RK805_LDOn, represents the DCDC
+or LDO number as described in RK805 datasheet.
+
+ - RK805_DCDC_REGn
+ - valid values for n are 1 to 4.
+ - RK805_LDO_REGn
+ - valid values for n are 1 to 3.
+
+Standard regulator bindings are used inside regulator subnodes. Check
+ Documentation/devicetree/bindings/regulator/regulator.txt
+for more details
+
+Gpio, Rtc, Pwrkey: the node are represented like below. When you attemp to enable
+ the module, setting the "status" to be "okay", otherwise "disabled".
+
+ rtc {
+ status = "okay";
+ };
+
+ pwrkey {
+ status = "okay";
+ };
+
+ gpio {
+ status = "okay";
+ };
+
+Example:
+ rk805: pmic@1c {
+ compatible = "rockchip,rk805";
+ status = "okay";
+ reg = <0x18>;
+ interrupt-parent = <&gpio2>;
