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 regulator-initial-mode, regulator-allowed-modes and regulator-mode could be
19 specified using mode values from dt-bindings/regulator/active-semi,8945a-regulator.h
20 file.
21
22 The valid names for regulators are:
23 REG_DCDC1, REG_DCDC2, REG_DCDC3, REG_LDO1, REG_LDO2, REG_LDO3, REG_LDO4.
