Subject: [PATCH 17/23] OMAPDSS: fix rgb-to-yuv color conv coefs
Date: Wed, 09 Dec 2015 15:59:45 +0000 [thread overview]
Message-ID: <1449676791-26304-18-git-send-email-tomi.valkeinen@ti.com> (raw)
The color conversion coefficients for RGB to YUV conversion (used with
writeback) don't result in the correct result. This patch sets the
correct coefficients.
