[PATCH 00/13] iommu/arm-smmu: Updates for 4.3

[Will Deacon]

Hi all,

This is the ARM SMMU driver queue I currently have for 4.3. The diffstat
is slightly noisy since Robin cleaned up the DMA API usage in the
io-pgtable code so the client drivers no longer need to perform
dma_map_page hacks in order to clean the CPU caches on non-coherent
systems.

Other changes include some MSI prep., a couple of minor fixes for
SMMUv3 and honouring of the dma-coherent property for SMMUv1/2.

In the absence of any issues, I plan to send a pull request to Joerg
later this week.

Cheers,

Will
