* Network

Currently defined compatibles:
- fsl,cpm1-scc-enet
- fsl,cpm2-scc-enet
- fsl,cpm1-fec-enet
- fsl,cpm2-fcc-enet (third resource is GFEMR)
- fsl,qe-enet

Example:

	ethernet@11300 {
		device_type = "network";
		compatible = "fsl,mpc8272-fcc-enet",
			     "fsl,cpm2-fcc-enet";
		reg = <11300 20 8400 100 11390 1>;
		local-mac-address = [ 00 00 00 00 00 00 ];
		interrupts = <20 8>;
		interrupt-parent = <&PIC>;
		phy-handle = <&PHY0>;
		fsl,cpm-command = <12000300>;
	};

* MDIO

Currently defined compatibles:
fsl,pq1-fec-mdio (reg is same as first resource of FEC device)
fsl,cpm2-mdio-bitbang (reg is port C registers)

Properties for fsl,cpm2-mdio-bitbang:
fsl,mdio-pin : pin of port C controlling mdio data
fsl,mdc-pin : pin of port C controlling mdio clock

Example:
	mdio@10d40 {
		device_type = "mdio";
		compatible = "fsl,mpc8272ads-mdio-bitbang",
			     "fsl,mpc8272-mdio-bitbang",
			     "fsl,cpm2-mdio-bitbang";
		reg = <10d40 14>;
		#address-cells = <1>;
		#size-cells = <0>;
		fsl,mdio-pin = <12>;
		fsl,mdc-pin = <13>;
	};
