I don't understand the IOMMU SID + mask really, but I think I've seen somewhere before like here that TZ can be a bit picky with the SIDs? https://lore.kernel.org/linux-arm-msm/opqdrmyj3y64nqqqmakjydn5rkspizufyeavm7ec7c7ufqz4wk@ey2a7bq3shfj/ https://lore.kernel.org/linux-arm-msm/11b5db69-49f5-4d7b-81c9-687d66a5cb0d@xxxxxxxxxx/ I don't quite want to risk having some obscure use case breaking because we cleaned up the dts ;) But if you're more sure than me that it won't break, let me know! > > It's also a bit weird that the mask has one more digit than the stream > ID.
