|
||
|
|
-------------------
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: "active-semi,act8846" or "active-semi,act8865" or "active-semi,act8600"
|
||
|
|
- reg: I2C slave address
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- system-power-controller: Telling whether or not this pmic is controlling
|
||
|
|
the system power. See Documentation/devicetree/bindings/power/power-controller.txt .
|
||
|
|
- active-semi,vsel-high: Indicates the VSEL pin is high.
|
||
|
|
If this property is missing, assume the VSEL pin is low(0).
|
||
|
|
|
||
|
|
Optional input supply properties:
|
||
|
|
- for act8600:
|
||
|
|
- vp1-supply: The input supply for DCDC_REG1
|
||
|
|
- vp2-supply: The input supply for DCDC_REG2
|
||
|
|
- vp3-supply: The input supply for DCDC_REG3
|
||
|
|
- inl-supply: The input supply for LDO_REG5, LDO_REG6, LDO_REG7 and LDO_REG8
|
||
|
|
SUDCDC_REG4, LDO_REG9 and LDO_REG10 do not have separate supplies.
|
||
|
|
- for act8846:
|
||
|
|
- vp1-supply: The input supply for REG1
|
||
|
|
- vp2-supply: The input supply for REG2
|
||
|
|
- vp3-supply: The input supply for REG3
|
||
|
|
- vp4-supply: The input supply for REG4
|
||
|
|
- inl1-supply: The input supply for REG5, REG6 and REG7
|
||
|
|
- inl2-supply: The input supply for REG8 and LDO_REG9
|
||
|
|
- inl3-supply: The input supply for REG10, REG11 and REG12
|
||
|
|
- for act8865:
|
||
|
|
- vp1-supply: The input supply for DCDC_REG1
|
||
|
|
- vp2-supply: The input supply for DCDC_REG2
|
||
|
|
- vp3-supply: The input supply for DCDC_REG3
|
||
|
|
- inl45-supply: The input supply for LDO_REG1 and LDO_REG2
|
||
|
|
- inl67-supply: The input supply for LDO_REG3 and LDO_REG4
|
||
|
|
|
||
|
|
Any standard regulator properties can be used to configure the single regulator.
|
||
|
|
regulator-initial-mode, regulator-allowed-modes and regulator-mode could be specified
|
||
|
|
for act8865 using mode values from dt-bindings/regulator/active-semi,8865-regulator.h
|
||
|
|
file.
|
||
|
|
|
||
|
|
The valid names for regulators are:
|
||
|
|
- for act8846:
|
||
|
|
REG1, REG2, REG3, REG4, REG5, REG6, REG7, REG8, REG9, REG10, REG11, REG12
|
||
|
|
- for act8865:
|
||
|
|
DCDC_REG1, DCDC_REG2, DCDC_REG3, LDO_REG1, LDO_REG2, LDO_REG3, LDO_REG4.
|
||
|
|
- for act8600:
|
||
|
|
DCDC_REG1, DCDC_REG2, DCDC_REG3, SUDCDC_REG4, LDO_REG5, LDO_REG6, LDO_REG7,
|
||
|
|
LDO_REG8, LDO_REG9, LDO_REG10,
