[Intel-gfx] [PATCH v3 0/8] Enable Transcoder Port Sync feature for tiled displays

[Manasi Navare]

First two patches are cleanup patches with no functional changes to
rename the existing update_crtc() hook to commit_modeset_enables() to better
match the drm_atomic naming conventions.
This also prepares to add new hook for ICL since that adds support for
transcoder port sync feature.

Rest of the patches enable transcoder port sync feature starting GEN 11
required to synchronize the two tile sent across two DP SST connectors.

This has been validated using IGT to enable Dell tiled monitor in a 2 pipe
2 port configuration.

Manasi Navare (8):
  drm/i915/display: Rename update_crtcs() to commit_modeset_enables()
  drm/i915/display: Move the commit_tail() disable sequence to
    commit_modeset_disables() hook

    Transcoder Port Sync
  drm/i915/display/icl: Enable TRANSCODER PORT SYNC for tiled displays
    across separate ports
  drm/i915/display/icl: HW state readout for transcoder port sync config
  drm/i915/display/icl: Enable master-slaves in trans port sync mode in
    correct order
