-Qualcomm Resource Power Manager (RPM) over SMD
+QCOM SMD RPM REGULATOR
 
-This driver is used to interface with the Resource Power Manager (RPM) found in
-various Qualcomm platforms. The RPM allows each component in the system to vote
-for state of the system resources, such as clocks, regulators and bus
-frequencies.
+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.
