Merge tag 'iommu-updates-v3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU Updates from Joerg Roedel: "Besides some fixes and cleanups in the code there are three more important changes to point out this time: * New IOMMU driver for the ARM SHMOBILE platform * An IOMMU-API extension for non-paging IOMMUs (required for upcoming PAMU driver) * Rework of the way the Tegra IOMMU driver accesses its registetrs - register windows are easier to extend now. There are also a few changes to non-iommu code, but that is acked by the respective maintainers." * tag 'iommu-updates-v3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (23 commits) iommu/tegra: assume CONFIG_OF in SMMU driver iommu/tegra: assume CONFIG_OF in gart driver iommu/amd: Remove redundant NULL check before dma_ops_domain_free(). iommu/amd: Initialize device table after dma_ops iommu/vt-d: Zero out allocated memory in dmar_enable_qi iommu/tegra: smmu: Fix incorrect mask for regbase iommu/exynos: Make exynos_sysmmu_disable static ARM: mach-shmobile: r8a7740: Add IPMMU device ARM: mach-shmobile: sh73a0: Add IPMMU device ARM: mach-shmobile: sh7372: Add IPMMU device iommu/shmobile: Add iommu driver for Renesas IPMMU modules iommu: Add DOMAIN_ATTR_WINDOWS domain attribute iommu: Add domain window handling functions iommu: Implement DOMAIN_ATTR_PAGING attribute iommu: Check for valid pgsize_bitmap in iommu_map/unmap iommu: Make sure DOMAIN_ATTR_MAX is really the maximum iommu/tegra: smmu: Change SMMU's dependency on ARCH_TEGRA iommu/tegra: smmu: Use helper function to check for valid register offset iommu/tegra: smmu: Support variable MMIO ranges/blocks iommu/tegra: Add missing spinlock initialization ...
