Qualcomm Technologies, Inc. Debug Clock Controller Binding

----------------------------------------------------------

Required properties :

- compatible: Shall contain "qcom,kona-debugcc".

- qcom,gcc: phandle to the GCC device node.

- qcom,videocc: phandle to the Video CC device node.

- qcom,camcc: phandle to the Camera CC device node.

- qcom,dispcc: phandle to the Display CC device node.

- qcom,npucc: phandle to the NPU CC device node.

- clock-names: Shall contain "xo_clk_src"

- clocks: phandle + clock reference to the CXO clock.

- #clock-cells : Shall contain 1.

Example:

	clock_debug: qcom,cc-debug {

		compatible = "qcom,kona-debugcc";

		qcom,gcc = <&clock_gcc>;

		qcom,videocc = <&clock_videocc>;

		qcom,camcc = <&clock_camcc>;

		qcom,dispcc = <&clock_dispcc>;

		qcom,npucc = <&clock_npucc>;

		clock-names = "xo_clk_src";

		clocks = <&clock_rpmh RPMH_CXO_CLK>;

		#clock-cells = <1>;

	};
