-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
-
-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"
-
-Example:
-
-soc {
-	...
-	bimc: interconnect@...000 {
-		reg = <0x00400000 0x80000>;
-		compatible = "qcom,qcs404-bimc";
