+i.MX busfreq driver binding
+----------------------------------------------------
+
+Required properties :
+- compatible : must be "fsl,busfreq-imx8mm"
+- #interconnect-cells : should contain 1
+- clocks : list of phandles and specifiers to all interconnect bus clocks
+- clock-names : clock names must include "dram-alt", "dram-apb", "dram-core",
+ "noc", "ahb" and "axi"
+
+Examples:
+
+ icc0: icc {
+ compatible = "fsl,busfreq-imx8mm";
+ #interconnect-cells = <1>;
+ clocks = <&clk IMX8MM_CLK_DRAM_ALT>,
+ <&clk IMX8MM_CLK_DRAM_APB>,
+ <&clk IMX8MM_CLK_DRAM_CORE>,
+ <&clk IMX8MM_CLK_NOC_DIV>,
+ <&clk IMX8MM_CLK_AHB_DIV>,
+ <&clk IMX8MM_CLK_MAIN_AXI>;
+ clock-names = "dram-alt", "dram-apb", "dram-core", "noc",
+ "ahb", "axi";
+ };
