Merge tag 'iommu-updates-v4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel:
- PASID table handling updates for the Intel VT-d driver. It implements
a global PASID space now so that applications usings multiple devices
will just have one PASID.
- A new config option to make iommu passthroug mode the default.
- New sysfs attribute for iommu groups to export the type of the
default domain.
- A debugfs interface (for debug only) usable by IOMMU drivers to
export internals to user-space.
- R-Car Gen3 SoCs support for the ipmmu-vmsa driver
- The ARM-SMMU now aborts transactions from unknown devices and devices
not attached to any domain.
- Various cleanups and smaller fixes all over the place.
