Subject: [RFC PATCH v2 08/13] media: add Mediatek's MM21 format
Date: Fri, 6 Sep 2019 20:55:08 +0900 [thread overview]
Message-ID: <20190906115513.159705-9-acourbot@chromium.org> (raw)
In-Reply-To: <20190906115513.159705-1-acourbot@chromium.org>
Add Mediatek's non-compressed 8 bit block video mode. This format is
produced by the MT8183 codec and can be converted to a non-proprietary
format with the MDP3 component.
Signed-off-by: Alexandre Courbot <acourbot@chromium.org>
