      7title: Qualcomm Resource Power Manager (RPM) over SMD
      8
      9description: |
     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
     12  to vote for state of the system resources, such as clocks, regulators and bus
     13  frequencies.
     14
     15  The SMD information for the RPM edge should be filled out.  See qcom,smd.yaml
     16  for the required edge properties.  All SMD related properties will reside
     17  within the RPM node itself.
     18
     19  The RPM exposes resources to its subnodes.  The rpm_requests node must be
     20  present and this subnode may contain children that designate regulator
     21  resources.
     22
     23  Refer to Documentation/devicetree/bindings/regulator/qcom,smd-rpm-regulator.yaml
     24  for information on the regulator subnodes that can exist under the
     25  rpm_requests.
