The existing CMRR fractional-timing code was permanently
disabled (if (!HAS_CMRR || true)), eDP-only, and relied
on a heuristic to guess when the fractional path was needed.
This series reworks it into a generic, debugfs-driven feature,
which later will be controlled via userspace when respective
uapi will be in-palce.

Mitul Golani (11):
  drm/i915/vrr: add per-CRTC vrr/cmrr debugfs control
  drm/i915/vrr: compute CMRR fractional timings generically
  drm/i915/vrr: dump CMRR state in the crtc state dump
  drm/i915/vrr: Move CMRR hw registers to fix refresh rate path
  drm/i915/vrr: Enable/Disable CMRR based on enable/disable
    preconditions
  drm/i915/display: Move CMRR crtc_state members under VRR
  drm/i915/vrr: Fix the CMRR enabling/disabling sequence
  drm/i915/vrr: Compare state and HW registers if platform supports CMRR
  drm/i915/vrr: Remove TODO as CMRR is exclusive to Adaptive mode
  drm/i915/vrr: Return from CMRR compute config in case of PSR2 enabled
  drm/i915/vrr: Enable cmrr
