Should've been a little more clear. Definitely each vendor will have their own combination of modes, but I mostly meant that I don't really see a use for VENDOR_AMD(compression_1) | VENDOR_OTHER(tiling_N), or VENDOR_ARM(afbc) | VENDOR_SAMSUNG(tiling_12x64). Each vendor's space would be free to use the 24 sub-bits as a bitmask, but I don't think there's a need for combining tokens from multiple vendor spaces.
