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 : See ethernet.txt file in the same directory
8
9Optional properties:
10- phy-reset-gpios : Should specify the gpio for phy reset
11- phy-reset-duration : Reset duration in milliseconds.  Should present
12  only if property "phy-reset-gpios" is available.  Missing the property
13  will have the duration be 1 millisecond.  Numbers greater than 1000 are
14  invalid and 1 millisecond will be used instead.
15- phy-supply : regulator that powers the Ethernet PHY.
16- phy-handle : phandle to the PHY device connected to this device.
17- fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.
18  Use instead of phy-handle.
19- fsl,num-tx-queues : The property is valid for enet-avb IP, which supports
20  hw multi queues. Should specify the tx queue number, otherwise set tx queue
21  number to 1.
22- fsl,num-rx-queues : The property is valid for enet-avb IP, which supports
23  hw multi queues. Should specify the rx queue number, otherwise set rx queue
24  number to 1.
25- fsl,magic-packet : If present, indicates that the hardware supports waking
26  up via magic packet.
27
28Optional subnodes:
29- mdio : specifies the mdio bus in the FEC, used as a container for phy nodes
30  according to phy.txt in the same directory

32Example:
33
34ethernet@83fec000 {
35	compatible = "fsl,imx51-fec", "fsl,imx27-fec";
36	reg = <0x83fec000 0x4000>;
37	interrupts = <87>;
38	phy-mode = "mii";
39	phy-reset-gpios = <&gpio2 14 0>; /* GPIO2_14 */
40	local-mac-address = [00 04 9F 01 1B B9];
41	phy-supply = <&reg_fec_supply>;
42};
43
44Example with phy specified:
45
46ethernet@83fec000 {
47	compatible = "fsl,imx51-fec", "fsl,imx27-fec";
48	reg = <0x83fec000 0x4000>;
49	interrupts = <87>;
50	phy-mode = "mii";
51	phy-reset-gpios = <&gpio2 14 0>; /* GPIO2_14 */
52	local-mac-address = [00 04 9F 01 1B B9];
53	phy-supply = <&reg_fec_supply>;
54	phy-handle = <&ethphy>;
55	mdio {
56		ethphy: ethernet-phy@6 {
57			compatible = "ethernet-phy-ieee802.3-c22";
58			reg = <6>;
59			max-speed = <100>;
60		};
61	};
62};
