This patch set is improving IO and fast wake lines calculation in PSR
code:

Use actual fast wake sync pulse count in calculation
Implement getter for IO buffer wake times and use that
Better presentation on how these are calculated

Also number of precharge pulses is increased by 2 pulses to fix
problems with certain panel models.

Jouni Högander (3):
  drm/i915/display: Add aux function pointer for fast wake sync pulse
    count
  drm/i915/psr: Improve fast and IO wake lines calculation
  drm/i915/display: Increase number of fast wake precharge pulses
