The interface mode is passed in the .config_init, which is configured
by the PCS driver, the hardware register is located in the PCS, this
driver will be pushed later.

Is this the same as how the syqca807x works? Can the PCS driver be
shared by these two drivers?

I am not sure syqca807x, would you point me the code path of this driver?

What i don't like at the moment is that we have two driver
developments going on at once for hardware which seems very similar,
but no apparent cooperation?

The PCS of qca8084 is the PHY PCS, which should be new PCS driver,
in the previous chips, we don't have this kind of PHY PCS.

No. PCS drivers are for MAC-side PCS drivers, not PHY-side PCS drivers.
