* 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@1c0b000 {

       compatible = "allwinner,sun4i-a10-emac";

       reg = <0x01c0b000 0x1000>;

       interrupts = <55>;

       clocks = <&ahb_gates 17>;

       phy = <&phy0>;
