| 2 | |
| 3 | Required properties: |
| 4 | - compatible: "maxim,max8907" |
| 5 | - reg: I2C slave address |
| 6 | - interrupts: The interrupt output of the controller |
| 7 | - mbatt-supply: The input supply for MBATT, BBAT, SDBY, VRTC. |
| 8 | - in-v1-supply: The input supply for SD1. |
| 9 | - in-v2-supply: The input supply for SD2. |
| 10 | - in-v3-supply: The input supply for SD3. |
| 11 | - in1-supply: The input supply for LDO1. |
| 12 | ... |
| 13 | - in20-supply: The input supply for LDO20. |
| 14 | - regulators: A node that houses a sub-node for each regulator within the |
| 15 | device. Each sub-node is identified using the regulator-compatible |
| 16 | property, with valid values listed below. The content of each sub-node |
| 17 | is defined by the standard binding for regulators; see regulator.txt. |

| 20 | - maxim,system-power-controller: Boolean property indicating that the PMIC |
| 21 | controls the overall system power. |
