[PATCH v9 2/4] iommu/arm-smmu: add NVIDIA implementation for ARM MMU-500 usage

2020-06-30 Thread Krishna Reddy
NVIDIA's Tegra194 SoC has three ARM MMU-500 instances. It uses two of ARM MMU-500s together to interleave IOVA accesses across them and must be programmed identically. The third SMMU instance is used as a regular ARM MMU-500 and it can either be programmed independently or identical to other two
