I am correcting the spelling mistake pointed by Mikko. The NVIDIA SMMUv2 implementation is getting used beyond Tegra194 SOC. To be able to use the smmu compatible string across multiple SOC's, "nvidia,smmu-v2" compatible string is chosen. Are you suggesting to make it soc specific and add another one in future? -KR
