-ACT88xx regulators
--------------------
-
-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,
