[Intel-gfx] [PATCH 0/9] drm/i915: Plumb crtc state to link training code

[Ville Syrjala]

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

Final pieces for plumbing the crtc state all the way down to the guts of
the link trainign code. Allows us to eliminate a bunch of adhoc state
from intel_dp, and nukes some of the remaining crtc->config usages.

I'm also fixing the DP spec violations around the vswing/pre-emphasis
selection. Someone pointed that issue out a while ago but there was
never any followup to that discussion AFAICS.

I had to neuter the phy test code since it has snuck in some duplicated
low level modeset code straight into the short hpd handler in intel_dp.c,
which is definitely not the way we want to do things. So that stuff
needs a real redesign at some point.

Ville Syrjälä (9):
  drm/i915: Fix cpt/ppt max pre-emphasis
  drm/i915: Fix ibx max vswing/preemph
  drm/i915: Fix ivb cpu edp vswing
  drm/i915: Add {preemph,voltage}_max() vfuncs
  drm/i915: Reverse preemph vs. voltage swing preference
  drm/i915: Fix DP_TRAIN_MAX_{PRE_EMPHASIS,SWING}_REACHED handling
  drm/i915: Replace some hand rolled max()s
  drm/i915: Plumb crtc_state to link training
  drm/i915: Eliminate intel_dp.regs.dp_tp_{ctl,status}
