Sashiko raises a reasonable question about what you'd do if it turned
out your current OSF GREEN doesn't quite comply with the specification
or needs some additional quirks.  Does it make sense to have a more
specific compatible with a fallback to the generic one?

Or given this is mostly about device firmware maybe this is fine.

Either way - would be good to add a note on why that doesn't make
sense in this patch description.

Thanks,
