QCOM SMD RPM REGULATOR

The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.
Because SMD is used as the communication transport mechanism, the RPM resides as
a subnode of the SMD. As such, the SMD-RPM regulator requires that the SMD and
RPM nodes be present.

Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd.txt for
information pertaining to the SMD node.

Please refer to Documentation/devicetree/bindings/soc/qcom/qcom,smd-rpm.txt for
information regarding the RPM node.
