    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
   10 
   11 Example:
