| TI LMU LM363x regulator device tree bindings |
| |
| LM363x regulator driver supports LM3631 and LM3632. |
| LM3631 has five regulators and LM3632 supports three regulators. |
| |
| Required property: |
| - compatible: "ti,lm363x-regulator" |
| |
| Optional properties: |
| LM3632 has external enable pins for two LDOs. |
| - enable-gpios: Two GPIO specifiers for Vpos and Vneg control pins. |
| The first entry is Vpos, the second is Vneg enable pin. |
| |
| Child nodes: |
| LM3631 |
| - vboost |
| - vcont |
| - voref |
| - vpos |
| - vneg |
| |
| LM3632 |
| - vboost |
| - vpos |
| - vneg |
| |
| Optional properties of a child node: |
| Each sub-node should contain the constraints and initialization. |
| Please refer to [1]. |
| |
| Examples: Please refer to ti-lmu dt-bindings [2]. |
