| 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 |
