Merge tag 'iommu-updates-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel:
- SMMU Updates from Will Deacon:
- SMMUv3:
- Support stalling faults for platform devices
- Decrease defaults sizes for the event and PRI queues
- SMMUv2:
- Support for a new '->probe_finalize' hook, needed by Nvidia
- Even more Qualcomm compatible strings
- Avoid Adreno TTBR1 quirk for DB820C platform
- Intel VT-d updates from Lu Baolu:
- Convert Intel IOMMU to use sva_lib helpers in iommu core
- ftrace and debugfs supports for page fault handling
- Support asynchronous nested capabilities
- Various misc cleanups
- Support for new VIOT ACPI table to make the VirtIO IOMMU
available on x86
- Add the amd_iommu=force_enable command line option to enable
the IOMMU on platforms where they are known to cause problems
- Support for version 2 of the Rockchip IOMMU
- Various smaller fixes, cleanups and refactorings
