Hello
  this series includes patches from two series previously sent:
https://lore.kernel.org/linux-media/20220119112024.11339-1-jacopo@jmondi.org/
https://lore.kernel.org/linux-media/20220211180216.290133-1-jacopo@jmondi.org/
v1:
https://lore.kernel.org/linux-media/20220214184318.409208-1-jacopo@jmondi.org/T/#t

Which can now be marked as superseded.

The first 2 patches performs the de-staging of the imx7-mipi-csis driver and
are now reviewed.

The rest of the series builds on top of the comment received on:
https://lore.kernel.org/linux-media/20220119112024.11339-3-jacopo@jmondi.org/

If DUAL pixel mode is used in the CSIS driver, then the CSI block of the IMX8MM
SoC needs to be operated in dual mode as well. To do so, use the image format
sample size to determine in the CSI bridge if dual or single mode should be
used.

Laurent could you test on MM to see if it works now ?

On top two small patches I was carrying in my tree to add more formats to the
CSIS driver, the last one with the caveat that RGB24 is transmitted on the wire
with one format and stored in memory with a different one.

Series based on top of the most recent media master branch.

Thanks

v1->v2:
- Remove per-SoC handling in CSI bridge and only use image formats
- Add TODO note to the staging driver
- Fix PIXEL_DUAL mode comments for imx-mipi-csis
- Add output format translation to imx-mipi-csis to handle RGB24
