I grep-ed amdgpu displayport atombios code, got udelay(400) only.
Did the same on drm *_dp_* files, got similar udelays with only a very slow
msleep (which seems justified there).
But I did not get any udelays with the range of 1ms for "retries". Maybe it
would be a good idea to a similar delay on non-DC displayport code? That would
give more time to "slow" displayort monitors to timeout on their side.
