[00/10] drm/i915/dp_mst: Add support for fractional link bpps

Message

This patchset adds support for fractional link bpps on MST links and
adds a way to verify this functionality via a connector debugfs entry
forcing the link bpp to a given value.

Imre Deak (10):
  drm/i915/dp: Use the correct connector while computing the link BPP
    limit on MST
  drm/i915/dp: Limit max link bpp properly to a fractional value on SST
  drm/i915/dp_mst: Add support for fractional link bpps on MST
  drm/i915/dp_mst: Enable fractional link bpps on MST
  drm/i915/display: Factor out intel_display_{min,max}_pipe_bpp()
  drm/i915/dp: Export intel_dp_dsc_min_src_compressed_bpp()
  drm/i915/dp: Use an intel_connector pointer everywhere
  drm/i915/hdmi: Use an intel_connector pointer everywhere
  drm/i915: Add support for forcing the link bpp on a connector
  drm/i915: Add force link bpp debugfs entry to connectors
