   1 Qualcomm RPM Clock Controller Binding
   2 ------------------------------------------------
   3 The RPM is a dedicated hardware engine for managing the shared
   4 SoC resources in order to keep the lowest power profile. It
   5 communicates with other hardware subsystems via shared memory
   6 and accepts clock requests, aggregates the requests and turns
   7 the clocks on/off or scales them on demand.

  13                         "qcom,rpmcc-msm8916", "qcom,rpmcc"
  14
  15 - #clock-cells : shall contain 1
