[PATCH 0/8][Questing][Unstable] Support AMD Image Signal Processing (ISP) unit V4.0

[You-Sheng Yang]

BugLink: https://bugs.launchpad.net/bugs/2110092

[Impact]

Miss AMD MIPI camera 4.0 support.

[Fix]

* https://lore.kernel.org/linux-media/20250828100811.95722-1-Bin.Du@amd.com/

[Test Case]

1. install kernel from -proposed channel with camera module installed,

2. Check device driver loaded:
```
$ media-ctl -p
Media controller API version 6.17.0

Media device information
------------------------
driver amd_isp_capture
model amd_isp41_mdev
...

$ gst-device-monitor-1.0 Video/Source
Probing devices...

Device found:

        name : amd_isp_capture (V4L2)
        class : Video/Source
        ...
```

3. Check camera functioning well:
```
$ gst-launch-1.0 v4l2src ! videoconvert ! autovideosink
```

[Where problems could occur]

New hardware support. Expect further updates.

[Other Info]

Unlike the previous driver implementations, the camera sensor is delegated
to sensor firmware fixed in bug 2119501. There is no more ov05c10 part as
done for linux-oem-6.11 and linux-oem-6.14, but ov05c10 is still used and
provided by ipu6-drivers.

Same with linux-oem-6.11 and linux-oem-6.14, there is no hard dependency
to libcamera to use AMD MIPI.

Nominiate for Questing as hwe-6.17 will be in the migration path for
linux-oem-6.14. And oem-6.17 of course.
