That's exactly what I object to. You're giving a false sense of
usability ("see, this driver is maintained, it even has DT support!"),
while the damn thing has not worked for quite a long time. And I don't
mean only the interrupt. The driver is not working properly on an SMP
system.

At that point, and unless someone is willing to step up and fix it, I'd
rather make it depend on CONFIG_BROKEN.
