In fact I do notice now that as long as you don't use any of the
optional phylink_mii_c22_pcs_* helpers in your PCS driver, then
struct phylink_pcs has pretty much zero dependency on struct mdio_device,
which means that I'm wrong and it should be completely within reach to
write a dedicated PCS driver for this hardware.

Yes, this was one of the design goals when I created phylink_pcs, as I
have exactly this situation with my hardware - PCS that do not have a
MDIO interface and do not conform to MDIO register layouts. So, I
explicitly ensured that phylink_pcs, just like the rest of phylink,
is not tied to any particular model of how hardware should look like.

Glad to see that this design decision is coming in handy for other
people now. :)
