You should have a cover letter here to provide some context.

There's a bunch of things that would need to be explained and / or
argued for here, in particular:
  - Why did you need to plumb it into sun6i-csi?
  - You're naming the CSI part as the A83t CSI, while MIPI-CSI has
been supported since the A31(?), is there a reason for that?
  - This is not documented anywhere, what did you base this work on?

Also, I think that documenting the general challenges you faced (which
were likely because of the first bullet point above) and how you
solved them here would be great to start a discussion if needed.

Finally, iirc, Hans requires a v4l2-compliance run for any new driver,
which isn't strictly the case for this driver, but isn't really *not*
the case either.

Thank you very much for the review, I will add all this context.

Kévin
