Hi Rahul,

I'm currently working on a patchset that tries to unify the infoframe
code that is currently duplicated for each driver. The latest code that
I have adds support for packing AVI, audio and vendor infoframes, so it
should cover all of what you're trying to do here. Furthermore there's a
helper that fill in a basic set of fields in the AVI infoframe from a
given drm_display_mode, based on code very similar to Stephane's patch
from Paulo Zanoni (Cc'ed).

Maybe we can try and make this work for Exynos as well. The code that I
have is tested on NVIDIA Tegra and should be easily portable to i915,
radeon and nouveau as well. I plan to do that as part of the patchset,
so I thought you may be interested in using the generic code as well.
The patches still need some cleanup but I think I can send them out
either later tonight or tomorrow.

Thierry
