   3 Qualcomm processors include an interface to communicate to the secure firmware.
   4 This interface allows for clients to request different types of actions.  These
   5 can include CPU power up/down, HDCP requests, loading of firmware, and other
   6 assorted actions.

   8 Required properties:
   9 - compatible: must contain "qcom,scm"
  10 - clocks: Should contain the core, iface, and bus clocks.
  11 - clock-names: Must contain "core" for the core clock, "iface" for the interface
  12   clock and "bus" for the bus clock.
