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.
Cheers,
Will
