Subject: [PATCH AUTOSEL 5.5 02/28] drm/bridge: dw-hdmi: fix AVI frame colorimetry
Date: Thu, 26 Mar 2020 19:23:31 -0400 [thread overview]
Message-ID: <20200326232357.7516-2-sashal@kernel.org> (raw)
In-Reply-To: <20200326232357.7516-1-sashal@kernel.org>
From: Jernej Skrabec <jernej.skrabec@siol.net>
[ Upstream commit e8dca30f7118461d47e1c3510d0e31b277439151 ]
CTA-861-F explicitly states that for RGB colorspace colorimetry should
be set to "none". Fix that.
