Currently DRM framework doesn't parse aspect ratio of a videomode while converting it from a umode->kmode or viceversa. This causes modeset of CEA modes with incorrect aspect ratio. While running HDMI complaince, tests (like 7-27) expect the DUT to apply the mode as per the VIC, but as driver does not consider the aspect ratio part while searching a mode from modedb, we end up setting mode with a wrong VIC, causing the test to fail. What this patch set does: Patch 1-2 - Adds aspect ratio flags in the DRM layer, in form of flags. - Adds parsing of aspect ratio, during conversion of a umode->kmode and viceversa. - Adds aspect ratio check while finding a mode, during modeset. Patch 3-5 - Adds some new aspect ratio defined in CEA-861-F specs to support HDMI 2.0 displays, in DRM and I915 layer.
