From: Ville Syrjälä <ville.syrjala at linux.intel.com>

A few DP related things:
- Fix 2.7 Gbps link training on g4x
- Adjust the idle pattern handling (most of this was part
  of my POST_LT_ADJ_REQ series earlier, but I reordered
  things to leave the actual POST_LT_ADJ_REQ support for
  later)
- shuffle the link training code a bit (again prep stuff
  for the POST_LT_ADJ_REQ support)

Ville Syrjälä (7):
  drm/i915/dp: Fix 2.7 Gbps DP_LINK_BW value on g4x
  drm/i915/dp: Don't switch to idle pattern before disable on pre-hsw
  drm/i915/dp: Clear DPCD training pattern before transmitting the idle
    pattern
  drm/i915/dp: Have intel_dp_get_adjust_train() tell us if anything
    changed
  drm/i915/dp: Move intel_dp_training_pattern()
  drm/i915/dp: Implement .set_idle_link_train() for everyone
  drm/i915/dp: Make .set_idle_link_train() mandatory
