+* VIA Velocity 10/100/1000 Network Controller
+
+Required properties:
+- compatible : Should be "via,velocity-vt6110"
+- reg : Address and length of the io space
+- interrupts : Should contain the controller interrupt line
+
+Optional properties:
+- no-eeprom : PCI network cards use an external EEPROM to store data. Embedded
+	devices quite often set this data in uboot and do not provide an eeprom.
+	Specify this option if you have no external eeprom.
+
+Examples:
+
+eth0@d8004000 {
+	compatible = "via,velocity-vt6110";
+	reg = <0xd8004000 0x400>;
+	interrupts = <10>;
+	no-eeprom;
+};
