I'm not sure what the "parent" MDIO bus node is supposed to represent.
  Is that that device that actually controls the muxing hardware

No.  It is the device that implements the master 802.3 clause {22,45} 
MDIO Station Management (STA) protocol.

Ah, I think I get it.  It is *the* MDIO node that would normally exist if
muxing we're necessary on the board.  From the looks of it, that node
would look exactly the same if you didn't need muxing?
