Subject: [git pull] IOMMU Updates for Linux v5.8
Hi Linus,
The following changes since commit 3d77e6a8804abcc0504c904bd6e5cdf3a5cf8162:
Linux 5.7 (2020-05-31 16:49:15 -0700)

iommu: Check for deferred attach in iommu_group_do_dma_attach() (2020-06-04 11:38:17 +0200)
----------------------------------------------------------------
IOMMU Updates for Linux v5.8
Including:
- A big part of this is a change in how devices get connected to
IOMMUs in the core code. It contains the change from the old
add_device()/remove_device() to the new
probe_device()/release_device() call-backs. As a result
functionality that was previously in the IOMMU drivers has
been moved to the IOMMU core code, including IOMMU group
allocation for each device.
The reason for this change was to get more robust allocation
of default domains for the iommu groups.
A couple of fixes were necessary after this was merged into
the IOMMU tree, but there are no known bugs left. The last fix
is applied on-top of the merge commit for the topic branches.
- Removal of the driver private domain handling in the Intel
VT-d driver. This was fragile code and I am glad it is gone
now.
- More Intel VT-d updates from Lu Baolu:
- Nested Shared Virtual Addressing (SVA) support to the
Intel VT-d driver
- Replacement of the Intel SVM interfaces to the common
IOMMU SVA API
- SVA Page Request draining support
- ARM-SMMU Updates from Will:
- Avoid mapping reserved MMIO space on SMMUv3, so that
it can be claimed by the PMU driver
- Use xarray to manage ASIDs on SMMUv3
- Reword confusing shutdown message
- DT compatible string updates
- Allow implementations to override the default domain
type
- A new IOMMU driver for the Allwinner Sun50i platform
- Support for ATS gets disabled for untrusted devices (like
Thunderbolt devices). This includes a PCI patch, acked by
Bjorn.
- Some cleanups to the AMD IOMMU driver to make more use of
IOMMU core features.
- Unification of some printk formats in the Intel and AMD IOMMU
drivers and in the IOVA code.
- Updates for DT bindings
- A number of smaller fixes and cleanups.
