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: | |
| 12 | pmic@5b { | |
| 13 | compatible = "active-semi,act8945a"; | |
| 14 | reg = <0x5b>; | |
| 15 | status = "okay"; | |
