QTI SCUBA Network-On-Chip interconnect driver binding

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



Required properties :

- compatible : shall contain only one of the following:

			"qcom,scuba-bimc",

			"qcom,scuba-system_noc",

			"qcom,scuba-config_noc",

			"qcom,scuba-clk_virt",

			"qcom,scuba-mmnrt_virt",

			"qcom,scuba-mmrt_virt",

- #interconnect-cells : should contain 1



reg : specifies the physical base address and size of registers

clocks : list of phandles and specifiers to all interconnect bus clocks

clock-names : clock names should include both "bus" and "bus_a"



The following are optional properties:



qcom,util-factor : Parameter that represents the DDR utilization factor

		to be used in aggregation scheme. It is represented as

		actual util-factor * 100.



Examples:



soc {

	...

	system_noc: interconnect@1880000 {

		reg = <0x1880000 0x60200>;

		compatible = "qcom,scuba-system_noc";

		qcom,util-factor = <142>;

		#interconnect-cells = <1>;

		clock-names = "bus", "bus_a";

		clocks = <&rpmcc RPM_SMD_SNOC_CLK>,

			<&rpmcc RPM_SMD_SNOC_A_CLK>;

	};



	config_noc: interconnect@1900000 {

		reg = <0x1900000 0x8200>;

		compatible = "qcom,scuba-config_noc";

		#interconnect-cells = <1>;

		clock-names = "bus", "bus_a";

		clocks = <&rpmcc RPM_SMD_CNOC_CLK>,

			<&rpmcc RPM_SMD_CNOC_A_CLK>;

	};

};
