Hi,
I was trying ov5640 camera sensor with the mainline BSP 6.0.0-rc3 kernel
and it fails to works, while it works quiet well on v5.18. When I
bisect, it points out to this commit 1f391df4 (media: v4l2-async: Use
endpoints in __v4l2_async_nf_add_fwnode_remote()) by Laurent Pinchart
and this is what it says in the logs :

So, now when I try to revert the change done by this commit, it still
fails. I assume there are a lot more changes following the commit that
could lead to this failure. Below are the logs.
Is there a way to get it to work without reverting any changes? Or Is
there something I'm missing or have to do any changes in the
corresponding files to get it to work?
The commit you reference wasn't meant to break anything, so there's
clearly something I've overlooked. Jacopo, have you noticed anything
similar when working on the ov5640 driver ?

This surprises me. I would have expected an issue with commit
1f391df44607 ("media: v4l2-async: Use endpoints in
__v4l2_async_nf_add_fwnode_remote()") to prevent the ov5640 from being
detected at all. Could you double-check the bisection, to verify that
commit 229fac6c44dc works and commit 1f391df44607 doesn't ? What
difference does it make in the full kernel log ?
Yes, the commit 229fac6c44dc works. This is the first commit 1f391df44607
("media: v4l2-async: Use endpoints in __v4l2_async_nf_add_fwnode_remote()")
that fails. The ov5640 driver is not detected and the /dev/media is not
present.
This is the difference in dmesg:
