[REBASE 0/5] Aspect ratio support in DRM layer

[Shashank Sharma]

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.

Ankit Nautiyal (1):
  drm: Handle aspect ratio in modeset paths

Shashank Sharma (2):
  drm: Add aspect ratio parsing in DRM layer
  drm: Add and handle new aspect ratios in DRM layer

aknautiy (2):
  drm: Add DRM client cap for aspect-ratio
  drm: Expose modes with aspect ratio, only if requested
