+Lantiq XWAY SoC FPI BUS binding
+============================
+
+
+-------------------------------------------------------------------------------
+Required properties:
+- compatible			: Should be one of
+					"lantiq,xrx200-fpi"
+- reg				: The address and length of the XBAR
+				  configuration register.
+				  Address and length of the FPI bus itself.
+- lantiq,rcu			: A phandle to the RCU syscon
+- lantiq,offset-endianness	: Offset of the endianness configuration
+				  register
+
+-------------------------------------------------------------------------------
+Example for the FPI on the xrx200 SoCs:
+	fpi@10000000 {
+		compatible = "lantiq,xrx200-fpi";
+		ranges = <0x0 0x10000000 0xf000000>;
+		reg =	<0x1f400000 0x1000>,
+			<0x10000000 0xf000000>;
+		lantiq,rcu = <&rcu0>;
+		lantiq,offset-endianness = <0x4c>;
+		#address-cells = <1>;
+		#size-cells = <1>;
+
+		gptu@e100a00 {
+			......
+		};
+	};
