This is v4 of [1] with the following changes: - Fix a race condition between connector setup and registration (added patch 1). - Rename DRM_DP_OVERHEAD_SSC to DRM_DP_OVERHEAD_SSC_REF_CLK (Ville, patch 9). - Fix setting crtc_state->fec_enable, once crtc_state->port_clock required for it is already set (patch 10). - Fix passing the correct fec_enable parameter to intel_dp_bw_fec_overhead() (patch 12). - Fix TU size, making it match the payload size in the payload table (Patch 13). - Apply the HBLANK expansion quirk whenever the HBLANK period is 300ns or less (Patch 21). - Fix refcounting of the DSC AUX decompression device (Stan, patch 25). - Fix HW readout/sanitize for the connector DSC decompression enabled state (patch 25). - Move intel_crtc_needs_modeset() check to callers of clear_pipe_update_flags_on_modeset_crtc() (Ville, patch 26). - Fix forcing modeset on CRTC due to a change in MST topology (Ville, patch 27). - Add missing DocBooks, fix typos.
