[PATCH 0/6] iommu/arm-smmu: misc features, new DT bindings

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
regulators).

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:

http://lists.linuxfoundation.org/pipermail/iommu/2014-July/009357.html

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
