1. Please describe the problem:

After the recent updates to the IPU7 code, we were expecting most of the mipi cameras to work, but it still does not work on the Dell 7450.

2. What is the Version-Release number of the kernel:

6.17.0-63.fc43.x86_64

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :

No, I don't believe it has worked before.

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

Reproduces 100% of the time. Boot a Dell 7450 on the latest Fedora 43 kernel, and run 'qcam' and it returns:

[0:48:09.135728964] [7397]  INFO Camera camera_manager.cpp:330 libcamera v0.5.2
[0:48:09.148843091] [7424]  INFO SimplePipeline simple.cpp:1687 No sensor found for /dev/media0
No camera detected

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:

This occurs with the kernel that contains the updates referred to in this advisory: FEDORA-2025-a2b653cff6: https://bodhi.fedoraproject.org/updates/FEDORA-2025-a2b653cff6

6. Are you running any modules that not shipped with directly Fedora's kernel?:

No

7. Please attach the kernel logs. Attached the output:

sudo journalctl -b 0 -k > kernel.txt
lsusb > lsusb.txt
ls -l /sys/bus/i2c/devices/ > i2c-devices.txt
ls -l /sys/bus/spi/devices/ > spi-devices.txt
