[0/5] drm/displayid: VESA vendor block and drm/i915 MSO use of it

We need the DisplayID VESA vendor block data for properly configuring
eDP MSO (Multi-SST Operation) pixel overlap.

I haven't actually tested this on a panel that requires the overlap, but
this is all pretty straightforward to prepare for that use case.

BR,
Jani.

Jani Nikula (5):
  drm/displayid: re-align data block macros
  drm/displayid: add DisplayID v2.0 data blocks and primary use cases
  drm/edid: parse the DisplayID v2.0 VESA vendor block for MSO
  drm/i915/edp: postpone MSO init until after EDID read
  drm/i915/edp: use MSO pixel overlap from DisplayID data
