> + vsp1_rpf_configure_autofld(rpf, cmd); Technically - if (rpf->interlaced) can only evaluate to true on DRM pipelines, which don't use the image partitioning. So it might be possible to argue that the vsp1_rpf_configure_autofld() call should be done in rpf_configure_frame(). Except I think it's reasonable to consider that the addresses and configuration of the frame are still just the 'first and only partition' - thus I think it's better to leave this here - and instead ensure that the requried DL is passed through.

I think it would make sense to move this to the tlb-optimise series indeed.

That's fine - but I've neglected to incorporate this into my v4 repost :-( If by any magic - v4 is suitable for integration already, and you're happy to take it into your tree - please feel free to update this comment.
