+* 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 : See ethernet.txt file in the same directory
+
+Optional properties:
+- 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.
+- phy-handle : phandle to the PHY device connected to this device.
+- fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.
+  Use instead of phy-handle.
+- fsl,num-tx-queues : The property is valid for enet-avb IP, which supports
+  hw multi queues. Should specify the tx queue number, otherwise set tx queue
+  number to 1.
+- fsl,num-rx-queues : The property is valid for enet-avb IP, which supports
+  hw multi queues. Should specify the rx queue number, otherwise set rx queue
+  number to 1.
+- fsl,magic-packet : If present, indicates that the hardware supports waking
+  up via magic packet.
+
+Optional subnodes:
+- mdio : specifies the mdio bus in the FEC, used as a container for phy nodes
+  according to phy.txt in the same directory
+
+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>;
+};
+
+Example with phy specified:
+
+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>;
+       phy-handle = <&ethphy>;
+       mdio {
+               ethphy: ethernet-phy@6 {
+                       compatible = "ethernet-phy-ieee802.3-c22";
+                       reg = <6>;
+                       max-speed = <100>;
+               };
+       };
+};
