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.
