+description:
+  RPM is a dedicated hardware engine for managing shared SoC resources,
+  which includes buses, clocks, power rails, etc.  The goal of RPM is
+  to achieve the maximum power savings while satisfying the SoC's
+  operational and performance requirements.  RPM accepts resource
+  requests from multiple RPM masters.  It arbitrates and aggregates
+  the requests, and configures the shared resources. The RPM masters
+  are the application processor, the modem processor, as well as hardware
+  accelerators. The RPM driver communicates with the hardware engine using
+  SMD.
