[PATCH 00/29] drm/i915: Add support for DP tunnel BW allocation

[Imre Deak]

Add support for detecting DP tunnels and enabling the BW allocation mode
on them.

Also fix hotplug detection issues during driver unloading and
system suspend/resume.

Imre Deak (29):
  drm/dp: Add DP tunnel DPCD registers
  drm/dp: Add drm_dp_max_dprx_data_rate()

  drm/i915/dp: Add intel_dp_max_link_data_rate()
  drm/i915/dp: Add support for DP tunnel BW allocation
  drm/i915/dp: Add DP tunnel atomic state and check BW limit
  drm/i915/dp: Account for tunnel BW limit in
    intel_dp_max_link_data_rate()
  drm/i915/dp: Compute DP tunel BW during encoder state computation
  drm/i915/dp: Allocate/free DP tunnel BW in the encoder enable/disable
    hooks
