nitpicky, but I think it would be nice say something like "stmmac_pcs
already contains the base address of the PCS registers. Pass that in
instead of recalculating the base address again" if I'm following the
motivation correctly.

Please drop the reg variable from the kerneldoc, you've annihilated it!
