      1QCOM Secure Channel Manager (SCM)
      2
      3Qualcomm processors include an interface to communicate to the secure firmware.
      4This interface allows for clients to request different types of actions.  These
      5can include CPU power up/down, HDCP requests, loading of firmware, and other
      6assorted actions.
      7
      8Required properties:
      9- compatible: must contain one of the following:
     10 * "qcom,scm-apq8064"
     11 * "qcom,scm-apq8084"
     12 * "qcom,scm-ipq4019"
     13 * "qcom,scm-ipq806x"
     14 * "qcom,scm-ipq8074"
     15 * "qcom,scm-mdm9607"
     16 * "qcom,scm-msm8226"
     17 * "qcom,scm-msm8660"
     18 * "qcom,scm-msm8916"

     34 * "qcom,scm-sm8450"
     35 and:
     36 * "qcom,scm"
     37- clocks: Specifies clocks needed by the SCM interface, if any:
     38 * core clock required for "qcom,scm-apq8064", "qcom,scm-msm8660" and
     39   "qcom,scm-msm8960"
     40 * core, iface and bus clocks required for "qcom,scm-apq8084",

     42- clock-names: Must contain "core" for the core clock, "iface" for the interface
     43  clock and "bus" for the bus clock per the requirements of the compatible.
     44- qcom,dload-mode: phandle to the TCSR hardware block and offset of the
     45		   download mode control register (optional)
     46
     47Example for MSM8916:
     48
     49	firmware {
     50		scm {
     51			compatible = "qcom,msm8916", "qcom,scm";
     52			clocks = <&gcc GCC_CRYPTO_CLK> ,
     53				 <&gcc GCC_CRYPTO_AXI_CLK>,
     54				 <&gcc GCC_CRYPTO_AHB_CLK>;
     55			clock-names = "core", "bus", "iface";
     56		};
     57	};
