ACT8865 regulator

ACT88xx regulators

-------------------



Required properties:

- compatible: "active-semi,act8865"

- compatible: "active-semi,act8846" or "active-semi,act8865"

- reg: I2C slave address



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.
