Subject[PATCH 01/12] HACK: increase timeout for drm_atomic_helper_wait_for_vblanks
Date
From: Quentin Schulz <quentin.schulz@free-electrons.com>

Due to the DP IP being simulated in a different and way slower way than
the rest of the hardware, increase the timeout in
drm_atomic_helper_wait_for_vblanks so that we don't miss the vblank
event.
