+Lantiq xRX200 GSWIP PMAC Ethernet driver
+==================================
+
+Required properties:
+
+- compatible   : "lantiq,xrx200-net" for the PMAC of the embedded
+               : GSWIP in the xXR200
+- reg          : memory range of the PMAC core inside of the GSWIP core
+- interrupts   : TX and RX DMA interrupts. Use interrupt-names "tx" for
+               : the TX interrupt and "rx" for the RX interrupt.
+
+Example:
+
+eth0: eth@E10B308 {
+       #address-cells = <1>;
+       #size-cells = <0>;
+       compatible = "lantiq,xrx200-net";
+       reg = <0xE10B308 0x30>;
+       interrupts = <73>, <72>;
+       interrupt-names = "tx", "rx";
+};
