Subject: [PATCH 4/4] drm: Add and handle new aspect ratios in DRM layer
Date: Wed,  3 Aug 2016 16:26:28 +0530	[thread overview]
Message-ID: <1470221788-30808-5-git-send-email-shashank.sharma@intel.com> (raw)
In-Reply-To: <1470221788-30808-1-git-send-email-shashank.sharma@intel.com>

HDMI 2.0/CEA-861-F introduces two new aspect ratios:
- 64:27
- 256:135

This patch:
-  Adds new DRM flags for to represent these new aspect ratios.
-  Adds new cases to handle these aspect ratios while converting
from user->kernel mode or viseversa.
