Device-Tree bindings for Active-semi ACT8945A MFD driver
2
+
3
+
Required properties:
4
+
- compatible: "active-semi,act8945a".
5
+
- reg: the I2C slave address for the ACT8945A chip
6
+
7
+
The chip exposes two subdevices:
8
+
- a regulators: see ../regulator/act8945a-regulator.txt
9
+
- a charger: see ../power/act8945a-charger.txt
