Subject: [PATCH v2 0/7] Nvidia Arm SMMUv2 Implementation
Date:   Mon, 2 Sep 2019 20:32:01 -0700
Message-ID: <1567481528-31163-1-git-send-email-vdumpa@nvidia.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Changes in v2:
- Prepare arm_smu_flush_ops for override.
- Remove NVIDIA_SMMUv2 and use ARM_SMMUv2 model as T194 SMMU hasn't modified ARM MMU-500.
- Add T194 specific compatible string - "nvidia,tegra194-smmu"
- Remove tlb_sync hook added in v1 and Override arm_smmu_flush_ops->tlb_sync() from implementation.
- Register implementation specific context/global fault hooks directly for irq handling.
- Update global/context interrupt list in DT and releant fault handling code in arm-smmu-nvidia.c.
- Implement reset hook in arm-smmu-nvidia.c to clear irq status and sync tlb.

v1 - https://lkml.org/lkml/2019/8/29/1588
