I think that all the drivers that are not converted to the common PWM
layer yet should depend on not enabling the common code. Once they
are all moved over, that dependency will go away.

Right. That's exactly what I meant. If we add depends on !HAVE_PWM to
the PWM symbol that should result in both options conflicting, and
therefore not being built at the same time.

But I would add it to all other ones then, not the generic one!

One question though: if the generic pwm implementation does not set
HAVE_PWM, how can a driver check its presence?
