Indeed, I based my definition on arch/arc/boot/dts/angel4.dts where phy 
is registered like this :

             phy0: ethernet-phy@0 {
                 reg = <1>;
             };

I think it's buggy there too, because I checked other dts files and they 
all put the same address
after @ and in reg register.

I'll fix this fot the next version.

Thanks

Best Regards,
Boris
