Hi Linus,

The following changes since commit f76349cf41451c5c42a99f18a9163377e4b364ff:

Linux 6.0-rc7 (2022-09-25 14:01:02 -0700)

Merge branches 'apple/dart', 'arm/mediatek', 'arm/omap', 'arm/smmu', 'virtio', 'x86/vt-d', 'x86/amd' and 'core' into next (2022-09-26 15:52:31 +0200)

----------------------------------------------------------------
IOMMU Updates for Linux v6.1:

Including:

- Removal of 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
