Jani Nikula (15):
  drm/mst: remove mgr parameter and debug logging from
    drm_dp_get_vc_payload_bw()
  drm/i915/mst: drop connector parameter from intel_dp_mst_bw_overhead()
  drm/i915/mst: drop connector parameter from intel_dp_mst_compute_m_n()
  drm/i915/mst: change return value of
    mst_stream_find_vcpi_slots_for_bpp()
  drm/i915/mst: remove crtc_state->pbn
  drm/i915/mst: add helper independent of MST for figuring out the TU
  drm/i915/mst: fixup TU calculation for 128b/132b SST
  drm/i915/ddi: enable 128b/132b TRANS_DDI_FUNC_CTL mode for UHBR SST
  drm/i915/ddi: 128b/132b SST also needs DP_TP_CTL_MODE_MST
  drm/i915/ddi: write payload for 128b/132b SST
  drm/i915/ddi: initialize 128b/132b SST DP2 VFREQ registers
  drm/i915/ddi: enable ACT handling for 128b/132b SST
  drm/i915/ddi: start distinguishing 128b/132b SST and MST at state
    readout
  drm/i915/ddi: handle 128b/132b SST in intel_ddi_read_func_ctl()
  drm/i915/dp: compute config for 128b/132b SST w/o DSC
