[Bug 2044991] Re: Intel IPU6 camera support for Dell MayaBay MLK

[Sebastien Bacher]

Could you add some rational of why you prefer to SRU a new version
rather than cherrypick selected fixes? The SRU team usually welcome have
some more context/something easier to review, in the current form it's
hard to tell if the new version includes more changes than what is
needed to fix this bug.

Bug description:
  [SRU Justification]

  [Impact]

  Missing Intel MIPI firmware for Intel IPU6 camera support for Dell
  MayaBay MLK.

  [Fix]

  Upstream release for support of ivsc in two additional camera sensors:
  * https://github.com/intel/ipu6-drivers/tree/Release_20231127
  * https://github.com/intel/ivsc-driver/tree/Release_20231127

  [Test Case]

  This is verified on MTL VSC platforms, as well as previous generations
  e.g. TGL and ADL.

  To actually verify the camera framework:
  ```
  # enable mantic-proposed, update the kernel, make sure you get 6.5.0-14.14
  # reboot into the 6.5.0-14.14 kernel
  $ sudo apt install intel-ipu6-dkms intel-vsc-dkms
  $ sudo add-apt-repository ppa:oem-solutions-group/intel-ipu6 -y -u
  $ sudo apt install gstreamer1.0-icamera v4l2-relayd
  ```
  In the above steps, make sure that only gstreamer1.0-icamera, v4l2-relayd, and their dependencies, are fetched from the oem-solutions-group PPA. Everything else must come from the mantic archive.

  And then browse https://webcamtests.com/ for testing.

  [Where problems could occur]

  This is a new platform with new combination of camera hardware. We've
  been verifying its functions and features to make sure it meets
  mandatory quality and stability, but it may still take updates for
  further tuning.

  [Other Info]

  While Intel Meteor Lake is only supported by linux-oem-6.5/jammy, and
  we're compiling linux-modules-{ipu6,ivsc} from dkms packages of
  Mantic, Noble/Mantic are therefore nominated.
