[PATCH 00/11] drm/i915/dp: Few MTL/DSC and a UHBR monitor fix

[Imre Deak]

This patchset fixes a few MTL/DSC 1.2 related issues and adds a
workaround for the native 5k at 60Hz uncompressed mode on a MediaTek/Dell
UHBR monitor, force-enabling DSC on it as required, similarly to the
existing HBLANK expansion quirk for Synaptics hubs.

Imre Deak (11):
  drm/i915/dp: Fix DSC line buffer depth programming
  drm/i915/dp_mst: Fix symbol clock when calculating the DSC DPT bpp
    limit
  drm/i915/dp_mst: Fix BW limit check when calculating DSC DPT bpp
  drm/i915/dp_mst: Account for channel coding efficiency in the DSC DPT
    bpp limit
  drm/i915/dp_mst: Account with the DSC DPT bpp limit on MTL
  drm/i915/dp_mst: Sanitize calculating the DSC DPT bpp limit
  drm/dp: Add drm_dp_uhbr_channel_coding_supported()
  drm/dp_mst: Factor out drm_dp_mst_port_is_logical()
  drm/dp_mst: Add drm_dp_mst_aux_for_parent()
  drm/i915/dp_mst: Make HBLANK expansion quirk work for logical ports
  drm/i915/dp_mst: Enable HBLANK expansion quirk for UHBR rates
