| 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 |
| Stephen Warren | 396f70b | 2012-09-24 13:25:03 -0600 | [diff] [blame] | 15 | device. Each sub-node is identified using the node's name (or the deprecated |
| 16 | regulator-compatible property if present), with valid values listed below. |
| 17 | The content of each sub-node is defined by the standard binding for |
| 18 | regulators; see regulator.txt. |
