[Intel-gfx] [PATCH 0/4] drm: DP++ adaptor support

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

While looking at a regression caused by i915's use of 12bpc HDMI mode,
I ended up reading the DP dual mode spec, and that lead to this patch
series.

I intentionally made the basics of the helper look somewhat like
Thierry's HDMI 2.0 SCDC stuff [1], except with a few less bugs :P

The entire series is available here:
git://github.com/vsyrjala/linux.git dp_dual_mode_2

Ville Syrjälä (4):
  drm: Add helper for DP++ adaptors
  drm/i915: Respect DP++ adaptor TMDS clock limit
  drm/i915: Enable/disable TMDS output buffers in DP++ adaptor as needed
  drm/i915: Determine DP++ type 1 DVI adaptor presence based on VBT
