* Freescale ColdFire DMA-FEC ethernet controller

Required properties:
- compatible: should be "fsl,mcf-dma-fec"
- reg: address and length of the register set for the device.
- rx-task: dma channel
- tx-task: dma channel
- rx-priority: dma channel
- tx-priority: dma channel
- rx-init: dma channel
- tx-init: dma channel

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@9000 {
	compatible = "fsl,mcf-dma-fec";
	reg = <0x9000 0x800>;
	mii-base = <0>;
	phy-addr = <0>;
	timeout-loop = <5000>;
	rx-task = <0>;
	tx-task = <1>;
	rx-piority = <6>;
	tx-piority = <7>;
	rx-init = <16>;
	tx-init = <17>;
	status = "disabled";
};
