7a400585 | 1 | QCOM SMD RPM REGULATOR |

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

100 | The regulator node houses sub-nodes for each regulator within the device. Each |
101 | sub-node is identified using the node's name, with valid values listed for each | |
