Hi Pratik,
I'm really looking forward to get this merged.
Just a few comments on the plane commit part below.
Cheers,

So far we have had only two commit styles, COMMIT_LEGACY
and COMMIT_UNIVERSAL. This patch adds another commit style
COMMIT_ATOMIC which makes use of drmModeAtomicCommit()
v2: (Marius)
i)Set CRTC_ID to zero while disabling plane
ii)Modified the log message in igt_atomic_prepare_plane_commit
https://patchwork.freedesktop.org/patch/71945/
v3: (Marius)Set FB_ID to zero while disabling plane
https://patchwork.freedesktop.org/patch/72179/
v4: (Maarten) Corrected the typo in commit message
https://patchwork.freedesktop.org/patch/72598/
v5: Added check for DRM_CLIENT_CAP_ATOMIC in igt_display_init
(Marius)
i)Removed unused props from igt_display_init
ii)Removed unused ret. Changed function to void
iii)Declare the variable before checking if we have
DRM_CLIENT_CAP_ATOMIC.
https://patchwork.freedesktop.org/patch/73505/
v6: (Jani) Corrected typo in commit message
https://patchwork.freedesktop.org/patch/74468/
v7: (Vlad & Maarten) Added is_atomic check for DRM_CLIENT_CAP_ATOMIC
in igt_display_init and igt_atomic_commit

Why resetting all these properties? It seems unnecessary.
If there is a reason for this, you might want to synchronize the fields
of igt_plane_t.

What happens if only the rotation has changed?
This condition should be outside the if (plane->fb_changed ||
plane->position_changed || plane->size_changed).

Overall I think this function would be a lot clearer if you just had a
test for each of the *_changed properties and just submitted the
associated properties in each case.
