+title: Qualcomm Resource Power Manager (RPM) over SMD
+
+description: |
+  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 SMD information for the RPM edge should be filled out.  See qcom,smd.txt
+  for the required edge properties.  All SMD related properties will reside
+  within the RPM node itself.
+
+  The RPM exposes resources to its subnodes.  The rpm_requests node must be
+  present and this subnode may contain children that designate regulator
+  resources.
+
+  Refer to Documentation/devicetree/bindings/regulator/qcom,smd-rpm-regulator.txt
+  for information on the regulator subnodes that can exist under the
+  rpm_requests.
