The use of mdio-parent-bus doesn't necessarily imply an mdio-mux. For
example, you'll also see it used in net/dsa/microchip,ksz.yaml.

You say this switch is also accessible over I2C. How are the internal
PHYs accessed in that case? Still over MDIO? If so, it would be nice to
have a unified scheme for both I2C-controlled switch and MDIO-controlled
switch, which is something that mdio-parent-bus would permit.
