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