  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>;
