Subject: [PATCH v2 0/8] iommu: The early demise of bus ops

v1: https://lore.kernel.org/linux-iommu/cover.1673978700.git.robin.murphy@arm.com/

Hi all,

Here's v2, now rebased on today's iommu/core and with just a few minor
changes. I've dropped "iommu: Pass device through ops->domain_alloc"
for now since I have nothing ready to take advantage of it yet, and I've
also realised that cleaning up set_pgtable_quirks will likely need yet
another change there anyway.

Cheers,
Robin.


Robin Murphy (8):
  iommu: Decouple iommu_present() from bus ops
  iommu: Validate that devices match domains
  iommu: Add lockdep annotations for group list iterators
  iommu: Factor out some helpers
  iommu: Switch __iommu_domain_alloc() to device ops
  iommu/arm-smmu: Don't register fwnode for legacy binding
  iommu: Retire bus ops
  iommu: Clean up open-coded ownership checks
