[Intel-gfx] [PATCH v2 0/4] drm/i915/icl: Fix TypeC Legacy HPD handling

[Imre Deak]

This is v2 of [1]. The changes in v2:
- Use VBT for detecting legacy ports. There was already a flag for this
  in VBT, I just missed it. Thanks for Siva for pointing that out. With
  that we have a detection that works all the time for DP ports as well.
- Remove a redundant special casing of legacy ports during disconnection
  in patch 3.
