I'm sorry, maybe I didn't express my concern clearly.

Any sizable list of exceptions in a Kconfig conditional has long term
maintainence costs.  If, for some reason, a new variant of support
for this chip arrives there will be a new Kconfig setting that would
need to be added here to your expressions.

That is insanely error prone, and I can guarantee it will get missed.

Having so many front end drivers for a chipset should be done in a
more modular manner, so that in fact they could all coexist if
