Merge tag 'iommu-updates-v4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel:
- Debugfs support for the Intel VT-d driver.
When enabled, it now also exposes some of its internal data
structures to user-space for debugging purposes.
- ARM-SMMU driver now uses the generic deferred flushing and fast-path
iova allocation code.
This is expected to be a major performance improvement, as this
allocation path scales a lot better.
- Support for r8a7744 in the Renesas iommu driver
- Couple of minor fixes and improvements all over the place
