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 .
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.
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,
