ACT88xx regulators
-------------------

Required properties:
- compatible: "active-semi,act8846" or "active-semi,act8865"
- 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 .

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.
