+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.
+- #clock-cells: from common clock binding; shall be set to 1 (multiple clock
+ outputs). See <dt-bindings/clock/rockchip,rk808.h> for clock IDs.
+
+Optional properties:
+- clock-output-names: From common clock binding to override the
+ default output clock name
+- rockchip,system-power-controller: Telling whether or not this pmic is controlling
+ the system power.
+- vcc1-supply: The input supply for DCDC_REG1
+- vcc2-supply: The input supply for DCDC_REG2
+- vcc3-supply: The input supply for DCDC_REG3
+- vcc4-supply: The input supply for DCDC_REG4
+- vcc6-supply: The input supply for LDO_REG1 and LDO_REG2
+- vcc7-supply: The input supply for LDO_REG3 and LDO_REG7
+- vcc8-supply: The input supply for SWITCH_REG1
+- vcc9-supply: The input supply for LDO_REG4 and LDO_REG5
+- vcc10-supply: The input supply for LDO_REG6
+- vcc11-supply: The input supply for LDO_REG8
+- vcc12-supply: The input supply for SWITCH_REG2
+
+Regulators: All the regulators of RK808 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 RK808 PMIC block are supported. Note that
+the 'n' in regulator name, as in DCDC_REGn or LDOn, represents the DCDC or LDO
+number as described in RK808 datasheet.
+
+ - DCDC_REGn
+ - valid values for n are 1 to 4.
+ - LDO_REGn
+ - valid values for n are 1 to 8.
+ - SWITCH_REGn
+ - valid values for n are 1 to 2
+
+Standard regulator bindings are used inside regulator subnodes. Check
+ Documentation/devicetree/bindings/regulator/regulator.txt
+for more details
