A few things needed to change: - HAS_PCH_SPLIT since ilk+ is not yet converted to this. - s/LVDS/intel_lvds->reg/ to prep for ilk conversion - replace the clock.p2 == 7 check with a is_dual_link check - s/adjusted_mode/intel_lvds->fixed_mode v2: Rebase on top of Jani Nikula's panel rework. I'm wondering whether we shouldn't add an attached_panel pointer to intel_encoder, to replace the encoder private ->attached_connector pointers, since that's essentially what we need.
