The generic Linux architecture for PHYs and binding them to a MAC via a phandle allows the PHY to be on any MDIO bus anywhere. DSA has some additional shortcuts to support 1:1 mapping if the switch has its own MDIO bus, without describing it in DT, but this is just in addition to the generic code. > Not json-schema documentation, don't care about: > - ar9331.txt > - lan9303.txt > - lantiq-gswip.txt > - marvell.txt The marvell switch can have up to 2 MDIO busses. If i remember correctly, there is also one switch which has one MDIO bus per port. Andrew
