Kernel-4.18.0-80.el8_act8865-regulator

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.

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,
