1Device-Tree bindings for Active-semi ACT8945A MFD driver
2
3Required properties:
4 - compatible: "active-semi,act8945a".
5 - reg: the I2C slave address for the ACT8945A chip
6
7The chip exposes two subdevices:
8 - a regulators: see ../regulator/act8945a-regulator.txt
9 - a charger: see ../power/act8945a-charger.txt
