Aha. I did not realize that was for same hardware... I should have
cc-ed you, I guess.

Can you elaborate? The chips are similar enough that single driver
makes sense, and we certainly want to maintain one driver, not 6
drivers differing only in .. what exactly?

a) No I did not, feel free to generate a diff.
b) Even if I did, why would that be a problem?

Well all 6 chips this driver supports seem to be similar enough, so
that single driver makes sense.
