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,
