[PATCH v4 00/12] Panel Replay + Adaptive sync

[Hogander, Jouni]

Hello DRM Maintainers,

I have two patches (01/12 and 02/12) in this set I would like to merge
via drm-intel/drm-intel-next. Is that ok to you? They are touching i915
display driver and drm_dp.h header and rest of the patch set is
depending on those changes. Can one of you ack those two patches?

Thank You in Advance,

Jouni Högander
