Changes in v10: Perform SMMU base ioremap before calling implementation init. Check for Global faults across both ARM MMU-500s during global interrupt. Check for context faults across all contexts of both ARM MMU-500s during context fault interrupt. Add new DT binding nvidia,smmu-500 for NVIDIA implementation. v9 - https://lkml.org/lkml/2020/6/30/1282 v8 - https://lkml.org/lkml/2020/6/29/2385 v7 - https://lkml.org/lkml/2020/6/28/347 v6 - https://lkml.org/lkml/2020/6/4/1018 v5 - https://lkml.org/lkml/2020/5/21/1114 v4 - https://lkml.org/lkml/2019/10/30/1054 v3 - https://lkml.org/lkml/2019/10/18/1601 v2 - https://lkml.org/lkml/2019/9/2/980 v1 - https://lkml.org/lkml/2019/8/29/1588 Krishna Reddy (5): iommu/arm-smmu: move TLB timeout and spin count macros iommu/arm-smmu: ioremap smmu mmio region before implementation init iommu/arm-smmu: add NVIDIA implementation for ARM MMU-500 usage dt-bindings: arm-smmu: add binding for Tegra194 SMMU iommu/arm-smmu: Add global/context fault implementation hooks .../devicetree/bindings/iommu/arm,smmu.yaml | 18 ++ MAINTAINERS | 2 + drivers/iommu/Makefile | 2 +- drivers/iommu/arm-smmu-impl.c | 3 + drivers/iommu/arm-smmu-nvidia.c | 278 ++++++++++++++++++ drivers/iommu/arm-smmu.c | 29 +- drivers/iommu/arm-smmu.h | 6 + 7 files changed, 328 insertions(+), 10 deletions(-) create mode 100644 drivers/iommu/arm-smmu-nvidia.c base-commit: e5640f21b63d2a5d3e4e0c4111b2b38e99fe5164 -- 2.26.2
