These are the patches from the from the prior series without the "fwspec
polishing":
 https://lore.kernel.org/r/0-v2-36a0088ecaa7+22c6e-iommu_fwspec_jgg@nvidia.com

Rebased onto Robin's patch:
 https://lore.kernel.org/all/16f433658661d7cadfea51e7c65da95826112a2b.1700071477.git.robin.murphy@arm.com/

Does a few things to prepare for the next:

- Clean up the call chains around dma_configure so the iommu_ops isn't being
  exposed.

- Add additional lockdep annotations now that we can.

- Replace the iommu_device_lock with iommu_probe_device_lock.

- Fix some missed places that need to call tegra_dev_iommu_get_stream_id()

Jason Gunthorpe (10):
  iommu: Remove struct iommu_ops *iommu from arch_setup_dma_ops()
  iommmu/of: Do not return struct iommu_ops from of_iommu_configure()
  iommu/of: Use -ENODEV consistently in of_iommu_configure()
  iommu: Mark dev_iommu_get() with lockdep
  iommu: Mark dev_iommu_priv_set() with a lockdep
  iommu: Replace iommu_device_lock with iommu_probe_device_lock
  acpi: Do not return struct iommu_ops from acpi_iommu_configure_id()
  iommu/tegra: Use tegra_dev_iommu_get_stream_id() in the remaining
    places
  ACPI: IORT: Cast from ULL to phys_addr_t
  ACPI: IORT: Allow COMPILE_TEST of IORT
