From: Tomi Valkeinen Date: Wed, 4 Nov 2015 15:10:52 +0000 (+0200) Subject: OMAPDSS: fix rgb-to-yuv color conv coefs X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7d18bbee78d39f2a69929f59920205efeee864e2;p=linux-beck.git OMAPDSS: fix rgb-to-yuv color conv coefs 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.
