[PATCH 0/8] 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.

Ankit Nautiyal (8):
  drm/i915/vrr: Use crtc_vsync_start/end for computing
    vrr.vsync_start/end
  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/display: Check if final vblank is sufficient for PSR features
  drm/i915/vrr: Recompute vblank_start for platforms with always-on VRR
    TG
  drm/i915/display: Add vblank_start adjustment logic for always-on VRR
    TG
  drm/i915/display: Prepare for vblank_delay for LRR
