This patch series is a re-attempt to enable aspect ratio support in DRM layer. Currently the aspect ratio information gets lost in translation during a user->kernel mode or vice versa. The old patch series (https://pw-emeril.freedesktop.org/series/10850/) had 4 patches, out of which 2 patches were reverted due to lack of drm client protection while loading the aspect information. This patch series, adds a DRM client option for aspect ratio, and loads aspect ratio flags, only when the client sets this cap. Also, to test this patch series there is a userspace implementation by Ankit Nautiyal in Wayland/weston layer: https://patchwork.freedesktop.org/patch/188125/ This, helps us in passing HDMI compliance test cases like 7-27, where the test equipment applies a CEA mode, and expects the exact VIC in the AVI infoframes.
