1 | MAX8907 regulator |
| 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. | |

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