Bug description:
  [SRU Justification]

  ========== ipu6-driver ==========

  [Impact]

  Missing Intel MIPI firmware for Meteor Lake platform.

  [Fix]

  Based on upstream tag
  https://github.com/intel/ipu6-drivers/releases/tag/Release_20231019,
  and an additional patch to enable/fix compilation of additional sensor
  modules.

  [Test Case]

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

  To actually verify the camera framework:
  ```
  $ sudo add-apt-repository ppa:oem-solutions-group/intel-ipu6
  $ sudo add-apt-repository ppa:canonical-hwe-team/intermediate-kernel
  $ sudo apt install linux-oem-22.04d-exp
  $ sudo apt install linux-modules-ipu6-oem-22.04d-exp
  $ sudo apt install linux-modules-ivsc-oem-22.04d-exp
  $ sudo apt install linux-modules-usbio-oem-22.04d-exp
  $ sudo apt install gstreamer1.0-icamera v4l2-relayd
  ```
  And then browse https://webcamtests.com/ for testing.

  [Where problems could occur]

  This is a new platform. We've been verifying its functions and features, and
  are still polishing it.

  [Other Info]

  While Intel Meteor Lake is only supported by linux-oem-6.5/jammy and
  linux/mantic and on, and yet the lastest stable driver was verified after Mantic was released, it's being proposed to Noble instead.

  ========== ivsc-driver ==========

  [Impact]

  Missing Intel MIPI firmware for Meteor Lake platform.

  [Fix]

  4 commits from the latest trunk branch on upstream repository
  https://github.com/intel/ivsc-driver.

  [Test Case]

  With all other changes in position, Intel VSC driver modules are to be
  loaded as a soft dependency of some selected camera sensor modules.
  LJCA modules should be loaded automatically on MTL platforms as well.

  To actually verify the camera framework:
  ```
  $ sudo add-apt-repository ppa:oem-solutions-group/intel-ipu6
  $ sudo add-apt-repository ppa:canonical-hwe-team/intermediate-kernel
  $ sudo apt install linux-oem-22.04d-exp
  $ sudo apt install linux-modules-ipu6-oem-22.04d-exp
  $ sudo apt install linux-modules-ivsc-oem-22.04d-exp
  $ sudo apt install linux-modules-usbio-oem-22.04d-exp
  $ sudo apt install gstreamer1.0-icamera v4l2-relayd
  ```
  And then browse https://webcamtests.com/ for testing.

  [Where problems could occur]

  While it changes how LJCA modules match from ACPI ID, it's also tested
  and verified on previous generations using IVSC, e.g. TGL, ADL.

  [Other Info]

  While Intel Meteor Lake is only supported by linux-oem-6.5/jammy and
  linux/mantic and on, and yet the lastest stable driver was verified after Mantic was released, it's being proposed to Noble instead.

  ========== linux/linux-oem-6.5 ==========

  [Impact]

  Need kernel driver fixes for int3472/iommu for Intel IPU6 platform on
  MTL.

  [Fix]

  Two fixes in need. One, we need IOMMU passthrough for MTL platform.
  The other, fix is for handshake pin support for Lattice MIPI
  aggregator.

  The Intel IPU6 camera drivers are not yet all upstreamed yet. So far
  Intel VSC, LJCA (the previous MIPI aggregator for ADL/RPL platforms) are
  in v6.6 already, and IPU6 ISYS is under upstream review. More components
  to come according to Intel.

  These two fixes are therefore for related components for not-yet fully
  upstreamed IPU6 as needed for out-of-tree dkms drivers.

  [Test Case]

  ```
  $ sudo dmesg | grep "Passthrough IOMMU for integrated Intel IPU"
  $ sudo dmesg | grep int3472
  # should have no "int3472-discrete INT3472:0c: GPIO type 0x12 unknown; the sensor may not work"
  ```

  [Where problems could occur]

  IOMMU Passthrough as necessary to enable IPU6 on Intel platforms, and
  it has been patching a few generations e.g. Bug 1989041 for Raptor
  Lake, Bug 1958004 for TGL and ADL. As IPU is not an external facing
  device which is not risky.

  For INT3472, the proposed patch might receive further updates per
  current upstream reviewers' opinions.

  [Other Info]

  Nominated for linux/mantic and oem-6.5/jammy as they're for MTL.

  ========== linux-firmware ==========

  [Impact]

  Missing Intel MIPI firmware for Meteor Lake platform.

  [Fix]

  Firmware blobs from upstream ipu6-camera-bins repository.

  [Test Case]

  With firmware loaded correctly, there should be firmware version
  printed:

    intel-ipu6 intel-ipu: FW version: 20220510

  For camera functions, we'll need also updates in the ipu6-drivers, ivsc-drivers
  dkms as well.

  [Where problems could occur]

  This is a new platform. We've been verifying its functions and features, and
  are still polishing it.

  [Other Info]

  While Intel Meteor Lake is only supported by linux-oem-6.5/jammy and
  linux/mantic, so only Jammy/Mantic are nominated.
