1QCOM SMD RPM REGULATOR
2
3The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.
4Because SMD is used as the communication transport mechanism, the RPM resides as
5a subnode of the SMD. As such, the SMD-RPM regulator requires that the SMD and
6RPM nodes be present.

8Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd.txt for
9information pertaining to the SMD node.
10
11Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd-rpm.txt for
12information regarding the RPM node.

210The regulator node houses sub-nodes for each regulator within the device. Each
211sub-node is identified using the node's name, with valid values listed for each
212of the pmics below.
