   1 Device-Tree bindings for regulators of Active-semi ACT8945A Multi-Function Device
   2
   3 Required properties:
   4  - compatible: "active-semi,act8945a", please refer to ../mfd/act8945a.txt.
   5
   6 Optional properties:
   7 - active-semi,vsel-high: Indicates if the VSEL pin is set to logic-high.
   8   If this property is missing, assume the VSEL pin is set to logic-low.
   9
  10 Optional input supply properties:
  11   - vp1-supply: The input supply for REG_DCDC1
  12   - vp2-supply: The input supply for REG_DCDC2
  13   - vp3-supply: The input supply for REG_DCDC3
  14   - inl45-supply: The input supply for REG_LDO1 and REG_LDO2
  15   - inl67-supply: The input supply for REG_LDO3 and REG_LDO4
  16
  17 Any standard regulator properties can be used to configure the single regulator.
  18
  19 The valid names for regulators are:
  20         REG_DCDC1, REG_DCDC2, REG_DCDC3, REG_LDO1, REG_LDO2, REG_LDO3, REG_LDO4.
