From 876f43c073d79ad3f14a4cebd1aea1f39fc4daf5 Mon Sep 17 00:00:00 2001 From: Shashank Sharma Date: Mon, 17 Oct 2016 17:34:37 +0530 Subject: [PATCH] drm: add picture aspect ratio flags 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.
