Hi all, This series adds support for the T8110 DARTs used for the Thunderbolt controllers on T600x SoCs and everywhere on T8112 SoCs. This new DART revision shuffles the registers around and removes support for multiple TTBR registers per SID (which never made sense on 16K configurations), but otherwise works much like the existing DART hardware. The pagetable format is the same as t600x, so no changes are needed there. Once reviewed, I'd like to merge patch #1 through the Asahi-SoC tree so we can start using it in device trees right away, instead of waiting for one release cycle. Patches #2 onwards should go through the IOMMU tree. v2: Addressed minor review comments (style nits and minor fixes).
