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
|
|
