If there is going to be any resend, please drop the comment. It's not
really helpful and makes it trickier to read.

I assume this matches existing drivers which do not use IDs but map the
binding to hardware value? I remember we talked about changing it, so if
something happened about this and it could be changed: please change.

I'm not aware of such discussion, and I don't really see the issue...
thoses are IDs, and yes they match the Hardware offsets, and ?


Otherwise, it's fine:
