Re: [PATCH 0/2 v6] drm/mediatek: Add support for 10-bit overlays

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
