+* Allwinner EMAC ethernet controller
+
+Required properties:
+- compatible: should be "allwinner,sun4i-a10-emac" (Deprecated:
+              "allwinner,sun4i-emac")
+- reg: address and length of the register set for the device.
+- interrupts: interrupt for the device
+- phy: see ethernet.txt file in the same directory.
+- clocks: A phandle to the reference clock for this device
+
+Example:
+
+emac: ethernet@01c0b000 {
+       compatible = "allwinner,sun4i-a10-emac";
+       reg = <0x01c0b000 0x1000>;
+       interrupts = <55>;
+       clocks = <&ahb_gates 17>;
+       phy = <&phy0>;
+};
