[Intel-gfx] [PATCH v3 4/4] drm: Add and handle new aspect ratios in DRM layer

2016-10-17 Thread Shashank Sharma 
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 vise versa.
