That is an odd combination. You enable the MDIO bus, but don't have
any PHYs on it, no phandles pointing to it. And you have this
fixed-link. It makes me think you have an Ethernet switch on the bus,
and this connects to it?

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.

What make/model of switch is it? Is it unmanaged, or does it use SPI
or I2C for management?

The switch is connected via RMII to the MAC and is managed over MDIO.
On our board, MDIO is not wired directly to the processor; instead, we
use a USB-to-MPSSE bridge (FT2232) to toggle the MDIO signals for
switch management.
So the MDIO bus in the DTS is not used, and enabling it there was a mistake.

O.K. What make/model?

I have to push back on you using a closed source user space driver,
given that i help maintain the Ethernet switch drivers...
I know there have been attempts to get GPIO support added for FT2232,
but i don't think any got as far as mainline. That is probably the
only part you are missing. You can describe USB devices in DT. So you
should be able to describe such a GPIO controller. You can then
instantiate an virtual,mdio-gpio driver to give you an MDIO bus. And
then add nodes for the switch using DSA.

The device is a Marvell 88E6393X switch. In our design, the BMC connects
to the device via RMII with fixed link parameters to retrieve ethernet.

Apologies for the confusion in my previous reply.
The BMC connects to the peer via an RMII fixed-link.
The link parameters are fixed at design time and there is no runtime
MDIO-managed PHY or switch control from the BMC.

So you use the USB-MDIO to program the EEPROM? The switch boots using
the settings in the EEPROM? It is then an unmanaged hub? You are not
using UMSD in userspace? That code looks terrible.
So if you connect multiple of these unmanaged hubs together in a loop,
your network disappears in a broadcast storm? Yes, you can use these
switches in a dumb mode, but it has consequences. If you let Linux
manage it, you gain a lot of functionality, such as STP, to break
loops.
But you seem to be opposed to this. At least add in a comment
explaining the purpose of the fixed link. DT describes hardware, so
there is no harm in describing the hardware, even if it is a comment
and not real properties.

Thanks for the comments.
I understand the concern about the DTS. I will add a clear comment in the
device tree explaining why a fixed-link is used and that the switch is
initialized via hardware straps and EEPROM, with no runtime management
from Linux.
