Thanks for the link, I wasn't aware of that patch. I like it in general, but 
there are some things I'd like to get addressed first:
* vr9_gphy_of_reg_init() writes uncoditionally to led3h and led3l even on
  PEf7071 which does not have this register at all
* Why is PHY_HAS_INTERRUPT commented out everywhere?
* ltq_phy_init and ltq_phy_exit can be simplified using phy_drivers_register
  and phy_drivers_unregister
* A mdio_device_id table is missing

Best regards,
Alexander
