[PATCH v5 00/19] Generic DT bindings for PCI IOMMUs and ARM SMMU

[Robin Murphy <robin.murphy-5wv7dgnIgG8@public.gmane.org>]

Hi all,

At long last I've finished the big SMMUv2 rework, so here's everything
all together for a v5. As a quick breakdown:

Patches 1-3 are the core PCI part, all acked and ready to go. No code
changes from v4.

Patch 4 is merely bugfixed from v4 for simplicity, as I've not yet
managed to take as close a look at Lorenzo's follow-on work as I'd like.

Patches 5-7 (SMMUv3) are mostly unchanged beyond a slight tweak to #5.

Patches 8-17 are the all-new SMMUv2 rework.

Patch 18 goes along with the fix already in 4.8-rc3 to help avoid 64-bit
DMA masks going wrong now that DMA ops will be enabled.

Finally, patch 19 addresses the previous problem of having to choose
between DMA ops or working MSIs. This is currently at the end as
moving it before #17 would require a further interim SMMUv2 patch, and
a 19-patch series is already quite enough...

I've pushed out a branch based on iommu/next to the usual place:

git://linux-arm.org/linux-rm iommu/generic-v5

Thanks,
Robin.
