I was trying to get to the bottom of the FDI fails on Brix Pro, and
thus eneded up going through the entire PCH modeset stuff for HSW.
While I did find a bunch of stuff missing/wrong, sadly I wasn't able
to make FDI training succeed on that machine. So in the end I simply
had to resort to getting rid of the CRT connector. And to add insult
to injury, the only way I could do that is to look at the VBT :(

Anwyay, here are the fruits of my labor. The whole thing is available
git://github.com/vsyrjala/linux.git hsw_pch_fixes

Ville Syrjälä (10):
  drm/i915: Don't register the CRT connector when it's fused off
  drm/i915: Don't register CRT connectro when DDI E can't be used
  drm/i915: Check VBT for CRT port presence on HSW/BDW
  drm/i915: Add "missing" break to haswell_get_ddi_pll()
  drm/i915: Disable CLKOUT_DP bending on LPT/WPT as needed
  drm/i915: Round to closest when computing the VGA dotclock for LPT-H
  drm/i915: Disable FDI after the CRT port on LPT-H
  drm/i915: Refactor LPT-H VGA dotclock disabling
  drm/i915: Disable LPT-H VGA dotclock during crtc disable
  drm/i915: Leave FDI running after failed link training on LPT-H
