1Device-Tree bindings for regulators of Active-semi ACT8945A Multi-Function Device
2
3Required properties:
4 - compatible: "active-semi,act8945a", please refer to ../mfd/act8945a.txt.
5
6Optional 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
10Optional 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
17Any standard regulator properties can be used to configure the single regulator.
18
19The valid names for regulators are:
20 REG_DCDC1, REG_DCDC2, REG_DCDC3, REG_LDO1, REG_LDO2, REG_LDO3, REG_LDO4.
