RK818 Power Management Integrated Circuit
|
||||
|
||||
Required properties:
|
||||
- compatible: "rockchip,rk818"
|
||||
- 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, LDO_REG2
|
||||
- vcc7-supply: The input supply for LDO_REG3, LDO_REG5, LDO_REG7
|
||||
- vcc8-supply: The input supply for LOD_REG4, LDO_REG6, LDO_REG8
|
||||
- vcc9-supply: The input supply for LDO_REG9, LDO_REG5, SWITCH_REG
|
||||
|
||||
Regulators: All the regulators of RK818 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 RK818 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 RK818 datasheet.
|
||||
|
||||
- DCDC_REGn
|
||||
- valid values for n are 1 to 4.
|
||||
- LDO_REGn
|
||||
- valid values for n are 1 to 9.
|
||||
|
||||
Standard regulator bindings are used inside regulator subnodes. Check
|
||||
Documentation/devicetree/bindings/regulator/regulator.txt
|
||||
