+* Freescale ColdFire FEC ethernet controller
+
+Required properties:
+- compatible: should be "fsl,mcf-fec"
+- reg: address and length of the register set for the device.
+
+Optional properties:
+- mii-base: index of FEC reg area, 0 for FEC0, 1 for FEC1
+- max-speed: max speedm Mbits/sec
+- phy-addr: phy address
+- timeout-loop: integer value for driver loops time out
+
+
+Example:
+
+fec0: ethernet@fc030000 {
+ compatible = "fsl,mcf-fec";
+ reg = <0xfc030000 0x400>;
+ mii-base = <0>;
+ phy-addr = <0>;
+ timeout-loop = <5000>;
+};
