The realtek-mdio driver is an MDIO driver and it must be inserted inside
an MDIO node.
+ The compatible string is only used to identify which (silicon) family the
+ switch belongs to. Roughly speaking, a family is any set of Realtek switches
+ whose chip identification register(s) have a common location and semantics.
+ The different models in a given family can be automatically disambiguated by
+ parsing the chip identification register(s) according to the given family,
+ avoiding the need for a unique compatible string for each model.
