[PATCH v2 0/9] drm/i915/prefill: Introduce helpers for prefill latency calculations

[Ville Syrjala <ville.syrjala@linux.intel.com>]

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

Introduce skl_prefill and various accompanying helpers to do
pipe prefill latency related stuff (vblank/guardband length
checks, and in the future reduced guardband length).

Still a bit rough in plaeces but hopefull good enough to
roll out.

v2: Always use worst case cdclk estimate for now
    Drop excessive debugs
    Fix missing <<16 for framestart_delay
    Use Ankit's intel_crtc_vblank_length()
    Some spit and polish here and there

Ankit Nautiyal (1):
  drm/i915/vblank: Add helper to get correct vblank length

Ville Syrjälä (8):
  drm/i915: Reject modes with linetime > 64 usec
  drm/i915/cdclk: Add prefill helpers for CDCLK
  drm/i915/cdclk: Add intel_cdclk_min_cdclk_for_prefill()
  drm/i915/dsc: Add prefill helper for DSC
  drm/i915/scaler: Add scaler prefill helpers
  drm/i915/wm: Add WM0 prefill helpers
  drm/i915/prefill: Introduce skl_prefill.c
  drm/i915/wm: Use skl_prefill
