Subject: [PATCH v2 04/11] drm: parse ycbcr 420 deep color information
Date: Tue, 30 May 2017 17:43:43 +0530	[thread overview]
Message-ID: <1496146430-11430-5-git-send-email-shashank.sharma@intel.com> (raw)
In-Reply-To: <1496146430-11430-1-git-send-email-shashank.sharma@intel.com>

CEA-861-F spec adds ycbcr420 deep color support information
in hf-vsdb block. This patch extends the existing hf-vsdb parsing
function by adding parsing of ycbcr420 deep color support from the
EDID and adding it into display information stored.
