Merge tag 'iommu-updates-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel:
- remove the bus_set_iommu() interface which became unnecesary because
of IOMMU per-device probing
- make the dma-iommu.h header private
- Intel VT-d changes from Lu Baolu:
- Decouple PASID and PRI from SVA
- Add ESRTPS & ESIRTPS capability check
- Cleanups
- Apple DART support for the M1 Pro/MAX SOCs
- support for AMD IOMMUv2 page-tables for the DMA-API layer.
The v2 page-tables are compatible with the x86 CPU page-tables. Using
them for DMA-API prepares support for hardware-assisted IOMMU
virtualization
- support for MT6795 Helio X10 M4Us in the Mediatek IOMMU driver
- some smaller fixes and cleanups
