* Freescale Fast Ethernet Controller (FEC)

Required properties:
- compatible : Should be "fsl,<soc>-fec"
- reg : Address and length of the register set for the device
- interrupts : Should contain fec interrupt
- phy-mode : String, operation mode of the PHY interface.
  Supported values are: "mii", "gmii", "sgmii", "tbi", "rmii",
  "rgmii", "rgmii-id", "rgmii-rxid", "rgmii-txid", "rtbi", "smii".

Optional properties:
- local-mac-address : 6 bytes, mac address
- phy-reset-gpios : Should specify the gpio for phy reset
- phy-reset-duration : Reset duration in milliseconds.  Should present
  only if property "phy-reset-gpios" is available.  Missing the property
  will have the duration be 1 millisecond.  Numbers greater than 1000 are
  invalid and 1 millisecond will be used instead.
- phy-supply: regulator that powers the Ethernet PHY.

Example:

ethernet@83fec000 {
	compatible = "fsl,imx51-fec", "fsl,imx27-fec";
	reg = <0x83fec000 0x4000>;
	interrupts = <87>;
	phy-mode = "mii";
	phy-reset-gpios = <&gpio2 14 0>; /* GPIO2_14 */
	local-mac-address = [00 04 9F 01 1B B9];
	phy-supply = <&reg_fec_supply>;
