Etnaviv detects them as: etnaviv-gpu 38000000.gpu: model: GC600, revision: 4653 etnaviv-gpu 38008000.gpu: model: GC520, revision: 5341 This seems to work fine more or less without any changes to the HWDB, which still might be needed in the future to correct some features, etc. [lst]: Added power domains and switched clock assignments to the new clock defines used for the composite clocks, instead of relying on the backwards compat defines.
