hmm, been trying to figure out all day how to make ucc_geth find my
fixed PHY without success. OF experts, please give me some hints.
My board is derived from the in tree mpc832x_mds bord and I am trying to
convert this part:
	mdio@2320 {
			#address-cells = <1>;
			#size-cells = <0>;
			reg = <2320 18>;
			device_type = "mdio";
			compatible = "ucc_geth_phy";

			phy3: ethernet-phy@03 {
				interrupt-parent = < &ipic >;
				interrupts = <11 8>;
				reg = <3>;
				device_type = "ethernet-phy";
			};
			phy4: ethernet-phy@04 {
				interrupt-parent = < &ipic >;
				interrupts = <12 8>;
				reg = <4>;
				device_type = "ethernet-phy";
			};
		};
into fixed PHYs, how do I do that?

Well, fixed phy didn't made it to have any representation in dts as of now, at least
what I am aware of, and it is just a platform device so far.

Speaking about it, I am recalling long-pending enhancement to unify fixed interface with
bus_id representation in gianfar (that is having numeric bus:device way).

About dts, the only options fixed phy can have, are speed and duplex, it does not trigger irq and
so on, and I see something like 

phy1: fixed-phy@01 {
	reg = <100 1>; /*100Mps, full duplex*/
	device_type = "ethernet-phy";
};

Looks resonable to me, although I think reg needs to be <d#100 1>

How do make ucc_geth find it?

PS.
   Could you send me the patch that fixes:
Device 'fixed@100:1' does not have a release() function, it is broken
and must be fixed.

Is this warning harmless?
