1RK808 Power Management Integrated Circuit 2 3Required properties: 4- compatible: "rockchip,rk808" 5- reg: I2C slave address 6- interrupt-parent: The parent interrupt controller. 7- interrupts: the interrupt outputs of the controller. 8- #clock-cells: from common clock binding; shall be set to 1 (multiple clock 9 outputs). See <dt-bindings/clock/rockchip,rk808.h> for clock IDs. 10 11Optional properties: 12- clock-output-names: From common clock binding to override the 13 default output clock name 14- rockchip,system-power-controller: Telling whether or not this pmic is controlling 15 the system power. 16- vcc1-supply: The input supply for DCDC_REG1 17- vcc2-supply: The input supply for DCDC_REG2 18- vcc3-supply: The input supply for DCDC_REG3 19- vcc4-supply: The input supply for DCDC_REG4 20- vcc6-supply: The input supply for LDO_REG1 and LDO_REG2 21- vcc7-supply: The input supply for LDO_REG3 and LDO_REG7 22- vcc8-supply: The input supply for SWITCH_REG1 23- vcc9-supply: The input supply for LDO_REG4 and LDO_REG5 24- vcc10-supply: The input supply for LDO_REG6 25- vcc11-supply: The input supply for LDO_REG8 26- vcc12-supply: The input supply for SWITCH_REG2 27- dvs-gpios: buck1/2 can be controlled by gpio dvs, this is GPIO specifiers 28 for 2 host gpio's used for dvs. The format of the gpio specifier depends in 29 the gpio controller. If DVS GPIOs aren't present, voltage changes will happen 30 very quickly with no slow ramp time. 31 32Regulators: All the regulators of RK808 to be instantiated shall be 33listed in a child node named 'regulators'. Each regulator is represented 34by a child node of the 'regulators' node. 35 36 regulator-name { 37 /* standard regulator bindings here */ 38 }; 39 40Following regulators of the RK808 PMIC block are supported. Note that 41the 'n' in regulator name, as in DCDC_REGn or LDOn, represents the DCDC or LDO 42number as described in RK808 datasheet. 43 44 - DCDC_REGn 45 - valid values for n are 1 to 4. 46 - LDO_REGn 47 - valid values for n are 1 to 8. 48 - SWITCH_REGn 49 - valid values for n are 1 to 2 50 51Standard regulator bindings are used inside regulator subnodes.
