   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.

   9 Required properties :
  10 - compatible : shall contain only one of the following. The generic
  11                compatible "qcom,rpmcc" should be also included.
  12
  13                         "qcom,rpmcc-msm8916", "qcom,rpmcc"
  14                         "qcom,rpmcc-msm8974", "qcom,rpmcc"
  15                         "qcom,rpmcc-apq8064", "qcom,rpmcc"
  16
  17 - #clock-cells : shall contain 1
