| title: Qualcomm RPM regulator |
| |
| description: |
| The Qualcomm RPM regulator is modelled as a subdevice of the RPM. |
| |
| Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,rpm.yaml |
| for information regarding the RPM node. |
| |
| The regulator node houses sub-nodes for each regulator within the device. |
| Each sub-node is identified using the node's name, with valid values listed |
| for each of the pmics below. |
