ethernet and mdio drivers share registers, so they use same unit-address:

arch/powerpc/boot/dts/tqm5200.dts:127.17-133.5: Warning (unique_unit_address): /soc5200@f0000000/ethernet@3000: duplicate unit-address (also used in node /soc5200@f0000000/mdio@3000)

arch/powerpc/boot/dts/mpc5200b.dtsi:218.23-223.5: Warning (unique_unit_address): /soc5200@f0000000/ethernet@3000: duplicate unit-address (also used in node /soc5200@f0000000/mdio@3000)
  also defined at arch/powerpc/boot/dts/digsy_mtc.dts:60.17-62.5
