Subject: [PATCH v3 13/14] drm/i915: set colorspace for ycbcr outputs
Date: Wed, 14 Jun 2017 23:17:44 +0530	[thread overview]
Message-ID: <1497462465-14066-14-git-send-email-shashank.sharma@intel.com> (raw)
In-Reply-To: <1497462465-14066-1-git-send-email-shashank.sharma@intel.com>

When HDMI output is other than RGB, we have to load the
corresponding colorspace of output mode. This patch fills
the colorspace of AVI infoframe as per the HDMI output mode.
