[PATCH 00/13] iommu: Retire bus_set_iommu()

[Robin Murphy]

Hi all,

Here's another chapter in my saga of moving to per-instance IOMMU ops -
iommu_present() and iommu_capable() cleanups will be ongoing for another
cycle or two, while this one is at least self-contained within the
subsystem. The next steps after this are making iommu_domain_alloc()
instance-aware - which should finish the public API - and pulling the
fwnode/of_xlate bits into __iommu_probe_device(). And then making sense
of whatever's left :)

For ease of review here I split out individual driver patches based on
whether there was any non-trivial change or affect on control flow; the
straightforward deletions are all lumped together since the whole series
needs applying together either way, but I'm happy to split the final
patch up further if anyone would like.

Patch #3 for AMD is based on Mario's SWIOTLB patch here:

https://lore.kernel.org/linux-iommu/20220404204723.9767-1-mario.limonciello@amd.com/

since that wants merging first as fix material. The series is also based
contextually (but not functionally) on my device_iommu_capable() patches
here:

https://lore.kernel.org/linux-iommu/cover.1649089693.git.robin.murphy@arm.com/

since those are pretty much good to go now (I'll send a slightly-tweaked
final version once the iommu/core branch is open).

Thanks,
Robin.
