Subject: [GIT PULL] iommu/arm-smmu: Updates for 5.12

Hi Joerg,

Please pull these Arm SMMU updates for 5.12. The biggest thing here isn't
actually Arm SMMU-related at all, but is the addition of a new driver for
the MT8192 IOMMU. I've included it here because it ended up touching
quite a bit of the io-pgtable code.

Please note that I've based this branch on the "iommu-fixes" tag I sent for
-rc4 to avoid conflicts with upstream.




The following changes since commit 694a1c0adebee9152a9ba0320468f7921aca647d:

  iommu/vt-d: Fix duplicate included linux/dma-map-ops.h (2021-01-12 16:56:20 +0000)
