Hi,
Commit 015060cb7795eac3 ("media: rcar-vin: enable field toggle after a
set number of lines for Gen3") was an attempt to fix the issue of
writing outside the capture buffer for VIN Gen3. Unfortunately it only
fixed a symptom of a problem to such a degree I could no longer
reproduce it.
Jacopo on the other hand working on a different setup still ran into the
issue. And he even figured out the root cause of the issue. When I
submitted the original VIN Gen3 support I had when addressing a review
comment missed to keep the crop and compose dimensions in sync with the
requested format resulting in the DMA engine not properly stopping
before writing outside the buffer.
This series reverts the incorrect fix in 1/2 and applies a correct one
in 2/2. I think this should be picked up for v4.18.
