* MCD (MobiCore Driver)



t-base is an operating system running in the secure world (TrustZone).

The t-base implementation consists of several components in the

secure world and the non-secure world (kernel and user space). The

MobiCore driver communicates with the t-base operating system that

exists in TrustZone.



Required properties:

  - compatible: Should be "qcom,mcd"

  - qcom,ce-hw-instance: should contain crypto HW instance

  - qcom,ce-device: Device number

  - clocks: Array of <clock_controller_phandle clock_reference> listing

            all the clocks that are accesed by this subsystem.

  - qcom,ce-opp-freq: indicates the CE operating frequency in Hz, changes from target to target.



Example:

	mcd {

		compatible = "qcom,mcd";

		qcom,ce-hw-instance = <0>;

		qcom,ce-device = <0>;

		clocks = <&clock_gcc clk_crypto_clk_src>,

			 <&clock_gcc clk_gcc_crypto_clk>,

			 <&clock_gcc clk_gcc_crypto_ahb_clk>,

			 <&clock_gcc clk_gcc_crypto_axi_clk>;

		clock-names = "core_clk_src", "core_clk",

				"iface_clk", "bus_clk";

		qcom,ce-opp-freq = <100000000>;

	};
