  drm/i915/dvo: Report LVDS attached to ch701x as connected
  Revert "drm/i915/bios: Reverse order of 100/120 Mhz SSC clocks"
  drm/i915: Verify Ironlake eDP presence on DP_A using the capability fuse
  drm/i915, intel_ips: When i915 loads after IPS, make IPS relink to i915.
  drm/i915/sdvo: Add hdmi connector properties after initing the connector
  drm/i915: Set the required VFMUNIT clock gating disable on Ironlake.
