Merge tag 'iommu-updates-v5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel:
- A big cleanup and optimization patch-set for the Tegra GART driver
- Documentation updates and fixes for the IOMMU-API
- Support for page request in Intel VT-d scalable mode
- Intel VT-d dma_[un]map_resource() support
- Updates to the ATS enabling code for PCI (acked by Bjorn) and Intel
VT-d to align with the latest version of the ATS spec
- Relaxed IRQ source checking in the Intel VT-d driver for some aliased
devices, needed for future devices which send IRQ messages from more
than on request-ID
- IRQ remapping driver for Hyper-V
- Patches to make generic IOVA and IO-Page-Table code usable outside of
the IOMMU code
- Various other small fixes and cleanups
