Hi, This series provides: (1) Unified SMMU driver among Tegra SoCs (2) Multiple Address Space support(MASID) in IOMMU(SMMMU) (3) Tegra IOMMU'able devices, most of platform devices are IOMMU'able. There's some discussion[1] about device population order, which can solve the following patches. ARM: dt: tegra114: Register AHB/IOMMU device first amba: Move AHB to core_initcall iommu/tegra: smmu: Move IOMMU to core_initcall Also "ARM: dma-mapping: Drop GFP_COMP for DMA memory allocations" may not be necessary by [2] Tested IOMMU functionality with T30 SD/MMC. Any further testing with T114 and/or other devices would be really appreciated.
