-QCOM Secure Channel Manager (SCM)
-
-Qualcomm processors include an interface to communicate to the secure firmware.
-This interface allows for clients to request different types of actions. These
-can include CPU power up/down, HDCP requests, loading of firmware, and other
-assorted actions.
-
-Required properties:
-- compatible: must contain one of the following:
- * "qcom,scm-apq8064"
- * "qcom,scm-apq8084"
- * "qcom,scm-ipq4019"

- * "qcom,scm-sm8450"
- and:
- * "qcom,scm"
-- clocks: Specifies clocks needed by the SCM interface, if any:
- * core clock required for "qcom,scm-apq8064", "qcom,scm-msm8660" and
- "qcom,scm-msm8960"
- * core, iface and bus clocks required for "qcom,scm-apq8084",
- "qcom,scm-msm8916", "qcom,scm-msm8953", "qcom,scm-msm8974" and "qcom,scm-msm8976"
-- clock-names: Must contain "core" for the core clock, "iface" for the interface
- clock and "bus" for the bus clock per the requirements of the compatible.
-- qcom,dload-mode: phandle to the TCSR hardware block and offset of the
- download mode control register (optional)
-- interconnects: Specifies the bandwidth requirements of the SCM interface (optional)

-Example for MSM8916:
-
- firmware {
- scm {
- compatible = "qcom,msm8916", "qcom,scm";
- clocks = <&gcc GCC_CRYPTO_CLK> ,
- <&gcc GCC_CRYPTO_AXI_CLK>,
- <&gcc GCC_CRYPTO_AHB_CLK>;
- clock-names = "core", "bus", "iface";
- };
