Bug description:
[SRU Justification]
[Impact]
Intel iommu was turned on by default in mainline build v5.15.5 or jammy
-generic kernel 5.15.0-12.12. This would breaks IPU6.
For TGL and ADL platforms, it has been fixed in bug 1958004 for oem-5.14 and
above. This patch adds a new ID for RPL.
[Fix]
Use IOMMU passthrough mode for IPU6 as it has its own iommu hardware.
[Test Case]
Apply the fix and kernel should print a new info line:
Passthrough IOMMU for integrated Intel IPU
and IPU6 camera should continue to work without intel_iommu=off
work-around.
[Where problems could occur]
No. That's what it should have been done.
[Other Info]
Nominates only oem-6.0 and unstable for we have RPL IPU6 enabled on oem-6.0
and newer.
========== original bug report ==========
Per
https://github.com/intel/ipu6-drivers/commit/89c6b99e4bec00a04b53f37cd8c3c01ce824a4ab,
an additional quirk is necessary for Intel IPU6 on Raptor Lake as
previous TGL/ADL do.
