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?
