just to clarify: in linux dts only the basics were taken from evb and changed if
needed (like iodomain, regulators).
mixed this with the barebox submsission where i mainly used the evb dts.

should i add a note in head that some parts are taken from EVB and vendors dts?
As this is my first new DTS, i want to be sure the legal notice is correct.

ok, on mdio0 there is the rtl8211 phy and on mdio1 there is the rtl8367rb switch,
so only 1 device per bus. I was not aware that 0 is broadcast.
