Subject: [RFC 3/3] drm/i915: Set colorspace by enabling Infoframe
Date: Tue, 24 Jul 2018 21:15:52 +0530 [thread overview]
Message-ID: <1532447152-23736-4-git-send-email-uma.shankar@intel.com> (raw)
In-Reply-To: <1532447152-23736-1-git-send-email-uma.shankar@intel.com>
Based on colorspace property value create an infoframe
with appropriate colorspace. This can be used to send an
infoframe packet with proper colorspace value set which
will help to enable wider color gamut like BT2020 on sink.
