    Merge tag 'iommu-updates-v5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu · 52a55252
    Linus Torvalds authored
    Pull iommu updates from Joerg Roedel:
    
     - batched unmap support for the IOMMU-API
    
     - support for unlocked command queueing in the ARM-SMMU driver
    
     - rework the ATS support in the ARM-SMMU driver
    
     - more refactoring in the ARM-SMMU driver to support hardware
       implemention specific quirks and errata
    
     - bounce buffering DMA-API implementatation in the Intel VT-d driver
       for untrusted devices (like Thunderbolt devices)
    
     - fixes for runtime PM support in the OMAP iommu driver
    
     - MT8183 IOMMU support in the Mediatek IOMMU driver
    
     - rework of the way the IOMMU core sets the default domain type for
       groups. Changing the default domain type on x86 does not require two
       kernel parameters anymore.
    
     - more smaller fixes and cleanups
