7 title: Qualcomm Resource Power Manager (RPM) over SMD
10 This driver is used to interface with the Resource Power Manager (RPM) found
11 in various Qualcomm platforms. The RPM allows each component in the system
15 The SMD information for the RPM edge should be filled out. See qcom,smd.txt
16 for the required edge properties. All SMD related properties will reside
17 within the RPM node itself.

7 title: QCOM SMD RPM REGULATOR
10 The Qualcomm RPM over SMD regulator is modelled as a subdevice of the RPM.
11 Because SMD is used as the communication transport mechanism, the RPM
12 resides as a subnode of the SMD. As such, the SMD-RPM regulator requires
13 that the SMD and RPM nodes be present.
