Subject: [PATCH v2 1/4] drm/bridge: dw-hdmi: fix AVI frame colorimetry
Date: Thu, 5 Mar 2020 00:25:09 +0100 [thread overview]
Message-ID: <20200304232512.51616-2-jernej.skrabec@siol.net> (raw)
In-Reply-To: <20200304232512.51616-1-jernej.skrabec@siol.net>
CTA-861-F explicitly states that for RGB colorspace colorimetry should
be set to "none". Fix that.
Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
Fixes: def23aa7e982 ("drm: bridge: dw-hdmi: Switch to V4L bus format and encodings")
