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 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.
