+Mediatek MT8183 interconnect binding
+
+MT8183 interconnect providers support dram bandwidth requirements. The provider
+is able to communicate with the DVFSRC and send the dram bandwidth to it.
+Provider nodes must reside within an DVFSRC device node.
+
+Required properties :
+- compatible : shall contain only one of the following:
+			"mediatek,mt8183-emi-icc"
+- #interconnect-cells : should contain 1
+
+Examples:
+
+dvfsrc@...12000 {
+	compatible = "mediatek,mt8183-dvfsrc";
+	reg = <0 0x10012000 0 0x1000>;
+	clocks = <&infracfg CLK_INFRA_DVFSRC>;
+	clock-names = "dvfsrc";
+	ddr_emi: interconnect {
+		compatible = "mediatek,mt8183-emi-icc";
+		#interconnect-cells = <1>;
+	};
+};
