NVIDIA's Tegra194 SoC has three ARM MMU-500 instances. It uses two of the ARM MMU-500s together to interleave IOVA accesses across them and must be programmed identically. This implementation supports programming the two ARM MMU-500s that must be programmed identically. The third ARM MMU-500 instance is supported by standard arm-smmu.c driver itself.
