[PATCH v3 0/2] iommu/arm-smmu: hard iova_to_phys

[Mitchel Humpherys]

This series introduces support for performing iova-to-phys translations via
the ARM SMMU hardware on supported implementations. We also make use of
some new generic macros for polling hardware registers.

v1..v2:

  - Renamed one of the iopoll macros to use the more standard `_atomic'
    suffix
  - Removed some convenience iopoll wrappers to encourage explicitness

v2..v3:

  - Remomved unnecessary `dev_name's
