1	* Freescale Fast Ethernet Controller (FEC)
2	
3	Required 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".
10	
11	Optional 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.
18	- phy-supply: regulator that powers the Ethernet PHY.
19	
20	Example:
21	
22	ethernet@83fec000 {
23		compatible = "fsl,imx51-fec", "fsl,imx27-fec";
24		reg = <0x83fec000 0x4000>;
25		interrupts = <87>;
26		phy-mode = "mii";
27		phy-reset-gpios = <&gpio2 14 0>; /* GPIO2_14 */
28		local-mac-address = [00 04 9F 01 1B B9];
29		phy-supply = <&reg_fec_supply>;
30	};
