1Lantiq XWAY SoC FPI BUS binding
2============================

5-------------------------------------------------------------------------------
6Required properties:
7- compatible			: Should be one of
8					"lantiq,xrx200-fpi"
9- reg				: The address and length of the XBAR
10				  configuration register.
11				  Address and length of the FPI bus itself.
12- lantiq,rcu			: A phandle to the RCU syscon
13- lantiq,offset-endianness	: Offset of the endianness configuration
14				  register

17Example for the FPI on the xrx200 SoCs:
18	fpi@10000000 {
19		compatible = "lantiq,xrx200-fpi";
20		ranges = <0x0 0x10000000 0xf000000>;
21		reg =	<0x1f400000 0x1000>,
22			<0x10000000 0xf000000>;
23		lantiq,rcu = <&rcu0>;
24		lantiq,offset-endianness = <0x4c>;
25		#address-cells = <1>;
26		#size-cells = <1>;

28		gptu@e100a00 {

30		};
