MAX8907 regulator
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: "maxim,max8907"
|
||
|
|
- reg: I2C slave address
|
||
|
|
- interrupts: The interrupt output of the controller
|
||
|
|
- mbatt-supply: The input supply for MBATT, BBAT, SDBY, VRTC.
|
||
|
|
- in-v1-supply: The input supply for SD1.
|
||
|
|
- in-v2-supply: The input supply for SD2.
|
||
|
|
- in-v3-supply: The input supply for SD3.
|
||
|
|
- in1-supply: The input supply for LDO1.
|
||
|
|
...
|
||
|
|
- in20-supply: The input supply for LDO20.
|
||
|
|
- regulators: A node that houses a sub-node for each regulator within the
|
||
|
|
device. Each sub-node is identified using the node's name (or the deprecated
|
||
|
|
regulator-compatible property if present), with valid values listed below.
|
||
|
|
The content of each sub-node is defined by the standard binding for
|
||
|
|
regulators; see regulator.txt.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- maxim,system-power-controller: Boolean property indicating that the PMIC
|
||
|
|
controls the overall system power.
|
||
|
|
|
||
|
|
The valid names for regulators are:
|
||
|
|
|
||
|
|
sd1, sd2, sd3, ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10,
|
||
|
|
ldo11, ldo12, ldo13, ldo14, ldo15, ldo16, ldo17, ldo18, ldo19, ldo20, out5v,
|
||
|
