Hi Inki, This is my final fight with DECON_UPDATE issues (I hope). My two previous patches fixed problems on panel path, this patchset fixes also TV path. The root cause of all evil was in incorrect DECON_CMU programming. Now it works correctly on: - panel, - TV, - both. I have not observed (so far) IOMMU faults, or vblank timeouts.
