We are hijacking another thread, but...

I don't understand you here. Who calls dsa_switch_register()?

I know of a board coming soon which has three switch chips on
it. There is one MDIO device in the Soc, but there is an external MDIO
multiplexor controlled via gpio lines, such that each switch has its
own MDIO bus. The DT binding does not support this currently, but the
underlying data structures do.

How do you envisage dsa_switch_register() to work in such a setup?
