| 2 | |
| 3 | LM363x regulator driver supports LM3631 and LM3632. |
| 4 | LM3631 has five regulators and LM3632 supports three regulators. |
| 5 | |
| 6 | Required property: |
| 7 | - compatible: "ti,lm363x-regulator" |
| 8 | |
| 9 | Optional properties: |
| 10 | LM3632 has external enable pins for two LDOs. |
| 11 | - enable-gpios: Two GPIO specifiers for Vpos and Vneg control pins. |
| 12 | The first entry is Vpos, the second is Vneg enable pin. |
| 13 | |
| 14 | Child nodes: |
| 15 | LM3631 |
| 16 | - vboost |
| 17 | - vcont |
| 18 | - voref |
| 19 | - vpos |
| 20 | - vneg |
| 21 | |
| 22 | LM3632 |
| 23 | - vboost |
| 24 | - vpos |
| 25 | - vneg |
| 26 | |
| 27 | Optional properties of a child node: |
| 28 | Each sub-node should contain the constraints and initialization. |
| 29 | Please refer to [1]. |
| 30 | |
| 31 | Examples: Please refer to ti-lmu dt-bindings [2]. |
