This series contains a some enhancements to the ARM SMMU driver. These
are mostly distinct but I'm sending them out in a single series since
they depend on each other for clean application.

The first two patches are related to power-saving features (clocks and

The third adds support for doing iova_to_phys through the SMMU
hardware on platforms that support it.

The fourth implements the recently merged generic DT bindings. For
reference, the discussion around the generic DT bindings is here:


The fifth and sixth handle some implementation-specific issues,
providing knobs in the device tree and a new domain attribute.

This series is based on on Will's iommu/pci branch.

Mitchel Humpherys (6):
  iommu/arm-smmu: add support for specifying clocks
  iommu/arm-smmu: add support for specifying regulators
  iommu/arm-smmu: add support for iova_to_phys through ATS1PR
  iommu/arm-smmu: implement generic DT bindings
  iommu/arm-smmu: support buggy implementations with invalidate-on-map
  iommu/arm-smmu: add .domain_{set,get}_attr for coherent walk control
