+L4 interconnect bindings
+
+These bindings describe the OMAP SoCs L4 interconnect bus.
+
+Required properties:
+- compatible : Should be "ti,omap2-l4" for OMAP2 family l4 core bus
+	       Should be "ti,omap2-l4-wkup" for OMAP2 family l4 wkup bus
+	       Should be "ti,omap3-l4-core" for OMAP3 family l4 core bus
+	       Should be "ti,omap4-l4-cfg" for OMAP4 family l4 cfg bus
+	       Should be "ti,omap4-l4-per" for OMAP4 family l4 per bus
+	       Should be "ti,omap4-l4-wkup" for OMAP4 family l4 wkup bus
+	       Should be "ti,omap5-l4-cfg" for OMAP5 family l4 cfg bus
+	       Should be "ti,omap5-l4-wkup" for OMAP5 family l4 wkup bus
+	       Should be "ti,dra7-l4-cfg" for DRA7 family l4 cfg bus
+	       Should be "ti,dra7-l4-wkup" for DRA7 family l4 wkup bus
+	       Should be "ti,am3-l4-wkup" for AM33xx family l4 wkup bus
+	       Should be "ti,am4-l4-wkup" for AM43xx family l4 wkup bus
+- ranges : contains the IO map range for the bus
+- reg : registers link agent and interconnect agent and access protection
+- reg-names : "la" for link agent, "ia0" to "ia3" for one to three
+              interconnect agent instances, "ap" for access if it exists
+
+Examples:
+
+l4: interconnect@48000000 {
+	compatible "ti,omap4-l4-per", "simple-bus";
+	reg = <0x48000000 0x800>,
+	      <0x48000800 0x800>,
+	      <0x48001000 0x400>,
+	      <0x48001400 0x400>,
+	      <0x48001800 0x400>,
+	      <0x48001c00 0x400>;
+	reg-names = "ap", "la", "ia0", "ia1", "ia2", "ia3";
+	#address-cells = <1>;
+	#size-cells = <1>;
+	ranges = <0 0x48000000 0x100000>;
+};
