There is no device to identify when the controller connects. The PHY's MDIO bus is registered by the driver that loads its firmware, seconds later, so phy-handle points at nothing yet. The chip does answer a Clause 45 identifier before the firmware runs, I read it on my board, so identification is not the blocker. > Or based on the fact that the phy has firmware-name. Nothing carries firmware-name here, the blob names are in the driver. I can add it to the phy node and key off that instead. Which do you want in v2?
