My apologies, I accidentally mangled the version history. It should actually read: v2: * Rebase and resolve merge conflicts with the AFBC patch. v3: * Moved 10-bit support detection to mtk_disk_ovl.c v4: * Moved formats to mtk_disp_ovl.c and mtk_disp_rdma.c v5: * Minor style adjustments per checkpatch.pl v6: * Refactor patch into patch series. * Add formats directly to private data.
