+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 :
+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:
+
+rpm-glink {
+ ...
+ rpm_requests: glink-channel {
+ ...
+ bimc: interconnect@0 {
+ 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@1 {
+ 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@2 {
+ 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>;
+ };
+ };
+};
