Imre Deak (6):
  drm/dp: Add quirk for Synaptics DSC throughput link-bpp limit
  drm/dp: Add helpers to query the branch DSC max throughput/line-width
  drm/i915/dp: Calculate DSC slice count based on per-slice peak
    throughput
  drm/i915/dp: Pass DPCD device descriptor to
    intel_dp_get_dsc_sink_cap()
  drm/i915/dp: Verify branch devices' overall pixel throughput/line
    width
  drm/i915/dp: Handle Synaptics DSC throughput link-bpp quirk
