This patchset enables the link training fallback on MST links between
UHBR and non-UHBR link rates. As a dependency it also switches the
fallback to happen in a link configuration sequence ordered by BW and
makes sure that the MST BW reported via the ENUM_PATH_RESOURCES message
is always up-to-date in the MST topology SW state.

Imre Deak (14):
  drm/dp_mst: Factor out function to queue a topology probe work
  drm/dp_mst: Add a helper to queue a topology probe
  drm/dp_mst: Simplify the condition when to enumerate path resources
  drm/i915/ddi: For an active output call the DP encoder sync_state()
    only for DP
  drm/i915/dp: Initialize the link parameters during HW readout
  drm/i915/dp: Send only a single modeset-retry uevent for a commit
  drm/i915/dp: Add a separate function to reduce the link parameters
  drm/i915/dp: Add helpers to set link training mode, BW parameters
  drm/i915/dp_mst: Reduce the link parameters in BW order after LT
    failures
  drm/i915/dp_mst: Configure MST after the link parameters are reset
  drm/i915/dp_mst: Queue modeset-retry after a failed payload BW
    allocation
  drm/i915/dp_mst: Reprobe the MST topology after a link parameter
    change
  drm/i915/dp_mst: Ensure link parameters are up-to-date for a disabled
    link
  drm/i915/dp_mst: Enable LT fallback between UHBR/non-UHBR link rates
