+RK816 Power Management Integrated Circuit
+
+Required properties:
+- compatible: "rockchip,rk816"
+- 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).
+
+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.
+- gpio-controller: Specifies that the node is a gpio controller when you attempt to
+ use the TS pin of RK816 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 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
+- vcc5-supply: The input supply for LDO_REG1, LDO_REG2, LDO_REG3
+- vcc6-supply: The input supply for LDO_REG4, LDO_REG5, LDO_REG6
+
+Regulators: All the regulators of RK816 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 RK816 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 RK816 datasheet.
+
+ - DCDC_REGn
+ - valid values for n are 1 to 4.
+ - LDO_REGn
+ - valid values for n are 1 to 6.
+
+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 attempt to enable
+ the module, setting the "status" to be "okay", otherwise "disabled".
+
+ rtc {
+ status = "okay";
+ };
+
+ pwrkey {
+ status = "okay";
+ };
+

If you say yes here you will get support for the

+ RTC of RK808/RK816 PMIC.
This driver can also be built as a module. If so, the module
will be called rk808-rtc.
