Merge tag 'iommu-updates-v5.2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel:
- ATS support for ARM-SMMU-v3.
- AUX domain support in the IOMMU-API and the Intel VT-d driver. This
adds support for multiple DMA address spaces per (PCI-)device. The
use-case is to multiplex devices between host and KVM guests in a
more flexible way than supported by SR-IOV.
- the rest are smaller cleanups and fixes, two of which needed to be
reverted after testing in linux-next.
