This patchset adds support for IOMMU API for Tegra20(GART) and Tegra30(SMMU). "struct iommu_ops" are implemented for both H/W IOMMU modules. Tested with "Ion memory manager" and "DMA mapping API"(*1). This was originally developed with Tegra specific IOMMU API(tegra_iovmm_*()) in: git://nv-tegra.nvidia.com/linux-2.6.git. v2: https://lkml.org/lkml/2011/12/15/203 v1: https://lkml.org/lkml/2011/11/17/111 *1: Reworking the DMA mapping code (especially on ARM) http://lwn.net/Articles/467509/ Hiroshi DOYU (2): ARM: IOMMU: Tegra20: Add iommu_ops for GART driver ARM: IOMMU: Tegra30: Add iommu_ops for SMMU driver arch/arm/mach-tegra/include/mach/smmu.h | 63 ++ drivers/iommu/Kconfig | 22 + drivers/iommu/Makefile | 2 + drivers/iommu/tegra-gart.c | 436 +++++++++++++ drivers/iommu/tegra-smmu.c | 1026 +++++++++++++++++++++++++++++++ 5 files changed, 1549 insertions(+), 0 deletions(-) create mode 100644 arch/arm/mach-tegra/include/mach/smmu.h create mode 100644 drivers/iommu/tegra-gart.c create mode 100644 drivers/iommu/tegra-smmu.c -- 1.7.5.4
