Ugh, yeah. I hate that convention, but better to be consistent, I guess.

They're not mutually exclusive because the vpif is the one that actually
maps the register range (since it's shared between vpif_display and
vpif_capture) so I guess I should just drop the reg property from the
vpif_capture node.

Thanks for the review,
