1* Freescale Fast Ethernet Controller (FEC)
2
3Required properties:
4- compatible : Should be "fsl,<soc>-fec"
5- reg : Address and length of the register set for the device
6- interrupts : Should contain fec interrupt
7- phy-mode : String, operation mode of the PHY interface.
8 Supported values are: "mii", "gmii", "sgmii", "tbi", "rmii",
9 "rgmii", "rgmii-id", "rgmii-rxid", "rgmii-txid", "rtbi", "smii".

11Optional properties:
12- local-mac-address : 6 bytes, mac address
13- phy-reset-gpios : Should specify the gpio for phy reset
14- phy-reset-duration : Reset duration in milliseconds. Should present
15 only if property "phy-reset-gpios" is available. Missing the property
16 will have the duration be 1 millisecond. Numbers greater than 1000 are
17 invalid and 1 millisecond will be used instead.

22 compatible = "fsl,imx51-fec", "fsl,imx27-fec";
23 reg = <0x83fec000 0x4000>;
24 interrupts = <87>;
25 phy-mode = "mii";
26 phy-reset-gpios = <&gpio2 14 0>; /* GPIO2_14 */
27 local-mac-address = [00 04 9F 01 1B B9];
