Subject: [PATCH 1/7] drm: Add P010, P012, P016 format definitions and fourcc
Date: Fri, 8 Feb 2019 19:17:19 +0530 [thread overview]
Message-ID: <1549633645-29616-2-git-send-email-swati2.sharma@intel.com> (raw)
In-Reply-To: <1549633645-29616-1-git-send-email-swati2.sharma@intel.com>
From: Juha-Pekka Heikkila <juhapekka.heikkila@gmail.com>
Add P010 definition, semi-planar yuv format where each component
is 16 bits 10 msb containing color value. First come Y plane [10:6]
followed by 2x2 subsampled Cr:Cb plane [10:6:10:6]
Add P012 definition, semi-planar yuv format where each component
is 16 bits 12 msb containing color value. First come Y plane [12:4]
followed by 2x2 subsampled Cr:Cb plane [12:4:12:4]
Add P016 definition, semi-planar yuv format where each component
is 16 bits. First come Y plane followed by 2x2 subsampled Cr:Cb
plane [16:16]
