+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";

+                       clock-names = "bus_clk", "bus_a_clk";
+                       clocks = <&rpmcc RPM_SMD_BIMC_CLK>,
+                               <&rpmcc RPM_SMD_BIMC_A_CLK>;
