[PATCH 00/10] Preparatory patches for guardband optimization

[Ankit Nautiyal <ankit.k.nautiyal@intel.com>]

Handle few cases which will need changes when guardband will no longer
be matched to vblank length.
- Fix the vblank_start evaluation.
- Fix PSR wake latency checks wrt to guradband.

Rev 2: PSR went through some changes recently, rebase the patches on latest
PSR changes.

Rev 3: Address comments from Ville and Jouni:
- Add a patch to move intel_dpll_crtc_compute_clock() early in the
  function.
- Merge patch to adjust vblank_start and the readout changes.
- Fix agument to alpm_config_valid()
- Add documentation for retionale behind PSR late-stage configuration.

Rev 4:
- Update pipe_mode->vblank_start and actually merge patch to adjust
  vblank_start and readout changes.

Rev 5:
- Reset other psr flags based on features that are dropped.

Rev 6:
- Make the order of panel_replay/sel_update flags consistent in Patch#5
- Add a patch to have separate function for
  intel_psr_set_non_psr_pipes()
- Split patch to introduce intel_psr_compute_config_late() from patch to
  check final vblank. Move Wa_18037818876 and
  intel_psr_set_non_psr_pipes() to intel_psr_compute_config_late().

Ankit Nautiyal (10):
  drm/i915/vrr: Use crtc_vsync_start/end for computing
    vrr.vsync_start/end
  drm/i915/display: Move intel_dpll_crtc_compute_clock early
  drm/i915/vrr:
    s/intel_vrr_compute_config_late/intel_vrr_compute_guardband
  drm/i915/vblank: Add helper to get correct vblank length
  drm/i915/psr: Consider SCL lines when validating vblank for wake
    latency
  drm/i915/psr: Introduce helper intel_psr_set_non_psr_pipes
  drm/i915/display: Introduce dp/psr_compute_config_late()
  drm/i915/psr: Check if final vblank is sufficient for PSR features
  drm/i915/display: Add vblank_start adjustment logic for always-on VRR
    TG
  drm/i915/display: Prepare for vblank_delay for LRR
