1 QCOM Secure Channel Manager (SCM)
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
9 - compatible: must contain one of the following:
22 - clocks: Specifies clocks needed by the SCM interface, if any:
23 * core clock required for "qcom,scm-apq8064", "qcom,scm-msm8660" and
25 * core, iface and bus clocks required for "qcom,scm-apq8084",
26 "qcom,scm-msm8916" and "qcom,scm-msm8974"
27 - clock-names: Must contain "core" for the core clock, "iface" for the interface
28 clock and "bus" for the bus clock per the requirements of the compatible.
29 - qcom,dload-mode: phandle to the TCSR hardware block and offset of the
30 download mode control register (optional)
