Subject: [PATCH v4 0/7] iommu, dma-mapping: Simplify arch_setup_dma_ops()

v3: https://lore.kernel.org/linux-iommu/cover.1707493264.git.robin.murphy@arm.com/

Hi all,

Since this ended up missing the boat for 6.9, here's a rebase and resend
with the additional tags from v3 collected.

Cheers,
Robin.


Robin Murphy (7):
  OF: Retire dma-ranges mask workaround
  OF: Simplify DMA range calculations
  ACPI/IORT: Handle memory address size limits as limits
  dma-mapping: Add helpers for dma_range_map bounds
  iommu/dma: Make limit checks self-contained
  iommu/dma: Centralise iommu_setup_dma_ops()
  dma-mapping: Simplify arch_setup_dma_ops()
