I didn't read super closely, but overall it makes sense to me..

Providing an in-kernel API will let someone else figure out how to
expose that to user space. The DT based scheme seems pretty nice.

Can you use this without DT overlay? Ie if I provide the FGPA
description as part of my boot time DT will it just work?
