[PATCH 1/5 v11] iommu/fsl: Make iova dma_addr_t in the iommu_iova_to_phys API.
From: Varun Sethi <hidden>
Date: 2013-03-28 20:02:18
Also in:
linux-iommu, lkml
Subsystem:
arm/qualcomm mailing list, exynos sysmmu (iommu) driver, iommu subsystem, qualcomm iommu, tegra iommu drivers, the rest · Maintainers:
Marek Szyprowski, Joerg Roedel, Will Deacon, Rob Clark, Thierry Reding, Linus Torvalds
This is required in case of PAMU, as it can support a window size of up to 64G (even on 32bit). Signed-off-by: Varun Sethi <redacted> --- changes in v11: - Made iova dma_addr_t instead of u64. - no change in v10. drivers/iommu/amd_iommu.c | 2 +- drivers/iommu/exynos-iommu.c | 2 +- drivers/iommu/intel-iommu.c | 2 +- drivers/iommu/iommu.c | 3 +-- drivers/iommu/msm_iommu.c | 2 +- drivers/iommu/omap-iommu.c | 2 +- drivers/iommu/shmobile-iommu.c | 2 +- drivers/iommu/tegra-gart.c | 2 +- drivers/iommu/tegra-smmu.c | 2 +- include/linux/iommu.h | 9 +++------ 10 files changed, 12 insertions(+), 16 deletions(-)
