Thanks for the clarification.
Yes, there is an Ethernet switch in the design.
The MAC is connected to the switch via RMII using a fixed-link
configuration.
However, the MDIO bus is not connected to the switch and is not
used on this board. Enabling the MDIO controller in the DTS was
a mistake on my side.
I will fix this in the next revision by disabling the unused MDIO
node, while keeping the fixed-link RMII connection to the switch.
