Sorry, this was mentioned in the cover letter, and patches to enable use
of the switch is incoming in a separate series very shortly.

"""
This also leaves out describing the RTL8367RB-VB switch as support for
the switch requires dt-binding and/or driver changes to make it work,
something that will be handled in a separate follow-up series.
"""

Basically the dt-bindings prevents describing a mdio child node, yet the
driver requires it. I have prepared a patch that relaxes the driver to
make it all work and it should be on the list shortly.

Jonas
