Merge tag 'iommu-updates-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel:
- Intel VT-d driver updates:
- Domain force snooping improvement.
- Cleanups, no intentional functional changes.
- ARM SMMU driver updates:
- Add new Qualcomm device-tree compatible strings
- Add new Nvidia device-tree compatible string for Tegra234
- Fix UAF in SMMUv3 shared virtual addressing code
- Force identity-mapped domains for users of ye olde SMMU legacy
binding
- Minor cleanups
- Fix a BUG_ON in the vfio_iommu_group_notifier:
- Groundwork for upcoming iommufd framework
- Introduction of DMA ownership so that an entire IOMMU group is
either controlled by the kernel or by user-space
- MT8195 and MT8186 support in the Mediatek IOMMU driver
- Make forcing of cache-coherent DMA more coherent between IOMMU
drivers
- Fixes for thunderbolt device DMA protection
- Various smaller fixes and cleanups
