Hi Linus,

The following changes since commit d434405aaab7d0ebc516b68a8fc4100922d7f5ef:

iommu: Streamline registration interface (2021-04-16 17:20:45 +0200)

----------------------------------------------------------------
IOMMU Updates for Linux v5.13

Including:

- Big cleanup of almost unsused parts of the IOMMU API by
Christoph Hellwig. This mostly affects the Freescale PAMU
driver.

- New IOMMU driver for Unisoc SOCs

- ARM SMMU Updates from Will:

- SMMUv3: Drop vestigial PREFETCH_ADDR support
- SMMUv3: Elide TLB sync logic for empty gather
- SMMUv3: Fix "Service Failure Mode" handling
- SMMUv2: New Qualcomm compatible string

- Removal of the AMD IOMMU performance counter writeable check
on AMD. It caused long boot delays on some machines and is
only needed to work around an errata on some older (possibly
pre-production) chips. If someone is still hit by this
hardware issue anyway the performance counters will just
return 0.

- Support for targeted invalidations in the AMD IOMMU driver.
Before that the driver only invalidated a single 4k page or the
whole IO/TLB for an address space. This has been extended now
and is mostly useful for emulated AMD IOMMUs.

- Several fixes for the Shared Virtual Memory support in the
Intel VT-d driver

- Mediatek drivers can now be built as modules

- Re-introduction of the forcedac boot option which got lost
when converting the Intel VT-d driver to the common dma-iommu
implementation.

- Extension of the IOMMU device registration interface and
support iommu_ops to be const again when drivers are built as
modules.
