Yes.

How should they get to the async list?

Actually, I'd go for "flash" and "focus-coil". There may be other
lens properties, such as zoom, mirror movement, lens identification,

Agreed, that would be nice.

I believe I can find the patch. But I'm not sure if I can port it to
the fwnode infrastructure anytime soon...
