I tend to agree with you.

Only APQ8060 here, but it's not even online after the reorg. Anyway, I assume that we have something alive and kicking for: - 1.1, 8226 (currently unusable, no IOMMU) - 1.2, 8974 (currently unusable, no IOMMU) - 1.6, 8916 - 1.8, 8939 - 1.9, 8994 (almost dead, I'd say) - 1.10, 8992 (almost dead, I'd say) - 1.11, 8956/76 It seems we can ignore (or drop) apq8084 (no activity since Dec 2019). Already in DPU: - 1.7, 8996 - 1.14, 8937 - 1.15, 8917 - 1.16, 8953 Which means: - port 8916, copy for 8939 / 8956/76 and hope it works - add LM-cursor support - deprecate mdp5, possibly moving it to EXPERT - add 8226 / 8974 once we have IOMMU - drop mdp5 -- With best wishes Dmitry
