   1 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
