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.
