 This is the subset of previous v12 series and includes only the fixes and

 This patch series includes,
 1] fixes for exynos-iommu driver build break
 2] includes several bug fixes and enhancements for the exynos-iommu driver
 3] code to handle multiple exynos sysmmu versions
 4] adding support for device tree
 Documentation/devicetree/bindings/iommu/samsung,sysmmu.txt

The patches look good to me, but please add a note into the samsung,sysmmu.txt
file explaining that the binding is incomplete and that it's possible to
change in incompatible ways when we add support for attaching devices to
the IOMMU through the generic IOMMU binding.
