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
