Subject: [PATCH 1/4] drm: add picture aspect ratio flags
Date: Wed,  3 Aug 2016 16:26:25 +0530	[thread overview]
Message-ID: <1470221788-30808-2-git-send-email-shashank.sharma@intel.com> (raw)
In-Reply-To: <1470221788-30808-1-git-send-email-shashank.sharma@intel.com>

This patch adds drm flag bits for aspect ratio information

Currently drm flag bits don't have field for mode's picture
aspect ratio. This field will help the driver to pick mode with
right aspect ratio, and help in setting right VIC field in avi
infoframes.
