Device-Tree bindings for regulators of Active-semi ACT8945A Multi-Function Device
|
|
|
|
Required properties:
|
|
- compatible: "active-semi,act8945a", please refer to ../mfd/act8945a.txt.
|
|
|
|
Optional properties:
|
|
- active-semi,vsel-high: Indicates if the VSEL pin is set to logic-high.
|
|
If this property is missing, assume the VSEL pin is set to logic-low.
|
|
|
|
Optional input supply properties:
|
|
- vp1-supply: The input supply for REG_DCDC1
|
|
- vp2-supply: The input supply for REG_DCDC2
|
|
- vp3-supply: The input supply for REG_DCDC3
|
|
- inl45-supply: The input supply for REG_LDO1 and REG_LDO2
|
|
- inl67-supply: The input supply for REG_LDO3 and REG_LDO4
|
|
|
|
Any standard regulator properties can be used to configure the single regulator.
|
|
|
|
The valid names for regulators are:
|
|
REG_DCDC1, REG_DCDC2, REG_DCDC3, REG_LDO1, REG_LDO2, REG_LDO3, REG_LDO4.
|
|

compatible = "active-semi,act8945a";
|
|
reg = <0x5b>;
|
|
