There's certainly some like Judging from our downstream code, I don't actually expect all of them will be used, except some being used yet not got upstream. > TSEC or NVDEC that we don't support (yet) upstream, but things like DC1 > and HC1 already have equivalents that we use, so I'm not sure how we'll > integrate these new ones. Downstream code groups those equivalents swgroups, so I think we can do similarly using tegra_smmu_group_soc like the existing one for display, if any of them gets upstream someday.
