Hi Andrew,
This block includes MII and MMD1 registers, which mainly configure the PLL
clocks, reset and calibration of the interface sgmii, there is no related
Clause 73 control register in this block.

O.K. What does it have in the MII ID registers? Does Linux think it is
a PHY and instantiating an generic PHY driver for it?

Hi Andrew,
it is the PLL related registers, there is no PHY ID existed in MII register 2, 3 of this block, so it can't be instantiated as the generic PHY device.
