[PATCH 00/14] drm/i915/dsb: Use chained DSBs for LUT programming

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Handle the DSB's DEwake shenanigans more elegantly
by chaining two DSBs together.

Ville Syrjälä (14):
  drm/i915: Calculate vblank delay more accurately
  drm/i915: Make vrr_{enabling,disabling}() usable outside
    intel_display.c
  drm/i915/dsb: Hook up DSB error interrupts
  drm/i915/dsb: Convert dewake_scanline to a hw scanline number earlier
  drm/i915/dsb: Shuffle code around
  drm/i915/dsb: Fix dewake scanline
  drm/i915/dsb: Account for VRR properly in DSB scanline stuff
  drm/i915/dsb: Precompute DSB_CHICKEN
  drm/i915/dsb: Introduce intel_dsb_wait_scanline_{in,out}()
  drm/i915/dsb: Introduce intel_dsb_chain()
  drm/i915/dsb: Allow intel_dsb_chain() to use DSB_WAIT_FOR_VBLANK
  drm/i915/dsb: Clear DSB_ENABLE_DEWAKE once the DSB is done
  drm/i915/dsb: s/dsb/dsb_color_vblank/
  drm/i915/dsb: Use chained DSBs for LUT programming
