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