ARM: SoC/iommu configuration for 3.19
The iomm-config branch contains work from Will Deacon, quoting his description:
This series adds automatic IOMMU and DMA-mapping configuration for
OF-based DMA masters described using the generic IOMMU devicetree
bindings. Although there is plenty of future work around splitting up
iommu_ops, adding default IOMMU domains and sorting out automatic IOMMU
group creation for the platform_bus, this is already useful enough for
people to port over their IOMMU drivers and start using the new probing
infrastructure (indeed, Marek has patches queued for the Exynos IOMMU).
The branch touches core ARM and IOMMU driver files, and the respective
maintainers (Russell King and Joerg Roedel) agreed to have the contents
merged through the arm-soc tree. The final version was ready just before
the merge window, so we ended up delaying it a bit longer than the rest,
but we don't expect to see regressions because this is just additional
infrastructure that will get used in drivers starting in 3.20 but is
unused so far.
