0001 Device-Tree bindings for Active-semi ACT8945A MFD driver
0002
0003 Required properties:
0004 - compatible: "active-semi,act8945a".
0005 - reg: the I2C slave address for the ACT8945A chip
0006
0007 The chip exposes two subdevices:
0008 - a regulators: see ../regulator/act8945a-regulator.txt
0009 - a charger: see ../power/act8945a-charger.txt
