Device-Tree bindings for Active-semi ACT8945A MFD driver |
|
|
|
Required properties: |
|
- compatible: "active-semi,act8945a". |
|
- reg: the I2C slave address for the ACT8945A chip |
|
|
|
The chip exposes two subdevices: |
|
- a regulators: see ../regulator/act8945a-regulator.txt |
|
- a charger: see ../power/act8945a-charger.txt |
|
|
|
Example: |
|

reg = <0x5b>; |
|

|
active-semi,vsel-high; |
