1 ACT88xx regulators
2 -------------------
3
4 Required properties:
5 - compatible: "active-semi,act8846" or "active-semi,act8865" or "active-semi,act8600"
6 - reg: I2C slave address
7
8 Optional properties:
9 - system-power-controller: Telling whether or not this pmic is controlling
10   the system power. See Documentation/devicetree/bindings/power/power-controller.txt .
11 - active-semi,vsel-high: Indicates the VSEL pin is high.
12   If this property is missing, assume the VSEL pin is low(0).
13
14 Optional input supply properties:
15 - for act8600:
16   - vp1-supply: The input supply for DCDC_REG1
17   - vp2-supply: The input supply for DCDC_REG2
18   - vp3-supply: The input supply for DCDC_REG3
19   - inl-supply: The input supply for LDO_REG5, LDO_REG6, LDO_REG7 and LDO_REG8
20   SUDCDC_REG4, LDO_REG9 and LDO_REG10 do not have separate supplies.
21 - for act8846:
22   - vp1-supply: The input supply for REG1
23   - vp2-supply: The input supply for REG2
24   - vp3-supply: The input supply for REG3
25   - vp4-supply: The input supply for REG4
26   - inl1-supply: The input supply for REG5, REG6 and REG7
27   - inl2-supply: The input supply for REG8 and LDO_REG9
28   - inl3-supply: The input supply for REG10, REG11 and REG12
29 - for act8865:
30   - vp1-supply: The input supply for DCDC_REG1
31   - vp2-supply: The input supply for DCDC_REG2
32   - vp3-supply: The input supply for DCDC_REG3
33   - inl45-supply: The input supply for LDO_REG1 and LDO_REG2
34   - inl67-supply: The input supply for LDO_REG3 and LDO_REG4
35
36 Any standard regulator properties can be used to configure the single regulator.
37
38 The valid names for regulators are:
39         - for act8846:
40         REG1, REG2, REG3, REG4, REG5, REG6, REG7, REG8, REG9, REG10, REG11, REG12
