The Qualcomm QCS404 platform has several buses that could be controlled
and tuned according to the bandwidth demand.

Signed-off-by: Georgi Djakov <georgi.djakov@linaro.org>

v3:
- Add a reg property and move the interconnect nodes under the "soc" node.

v2:
- No changes.

+Qualcomm QCS404 Network-On-Chip interconnect driver binding
+-----------------------------------------------------------
+
+Required properties :
+- compatible : shall contain only one of the following:
+			"qcom,qcs404-bimc"
+			"qcom,qcs404-pcnoc"
+			"qcom,qcs404-snoc"
+- #interconnect-cells : should contain 1
+
+Optional properties :
+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_clk" and "bus_a_clk"
+
+Example:
+
+soc {
+	...
+	bimc: interconnect@400000 {
+		reg = <0x00400000 0x80000>;
+		compatible = "qcom,qcs404-bimc";
+		#interconnect-cells = <1>;
+		clock-names = "bus_clk", "bus_a_clk";
+		clocks = <&rpmcc RPM_SMD_BIMC_CLK>,
+			<&rpmcc RPM_SMD_BIMC_A_CLK>;
+	};
+
+	pnoc: interconnect@500000 {
+		reg = <0x00500000 0x15080>;
+		compatible = "qcom,qcs404-pcnoc";
+		#interconnect-cells = <1>;
+		clock-names = "bus_clk", "bus_a_clk";
+		clocks = <&rpmcc RPM_SMD_PNOC_CLK>,
+			<&rpmcc RPM_SMD_PNOC_A_CLK>;
+	};
+
+	snoc: interconnect@580000 {
+		reg = <0x00580000 0x23080>;
+		compatible = "qcom,qcs404-snoc";
+		#interconnect-cells = <1>;
+		clock-names = "bus_clk", "bus_a_clk";
+		clocks = <&rpmcc RPM_SMD_SNOC_CLK>,
+			<&rpmcc RPM_SMD_SNOC_A_CLK>;
+	};
+};
