OK let's not do that then.

OK we have consensus on this.

Either they can be enum or defined to bool true/false. Not really
sure what is best. But intuitively enum "feels better" for me.

I rather want it all to happen at once. One preparatory commit
adding the new types and one sed script to refactor the whole
lot. Not gradual switchover.

The reason is purely administrative: we have too many refactorings
lagging behind, mainly the GPIO descriptors that have been
lagging behind for what is it? 5 years? 10? GPIO irqchips also dragged
out for way too long. We can't keep doing things gradually like
this, it takes too much time and effort.

I don't want any more "in-transition-indefinitely" stuff in the GPIO
subsystem if I can avoid it.

Therefore I would advice to switch it all over at the end of a merge
window and be done with it.
