[Intel-gfx] [PATCH v2 0/4] drm/i915: Start reordering modeset clock calculations

[Ville Syrjala]

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

Start reordering when we do the clock/dpll calculations
during the atomic check. The eventual goals are:
- back feed the actually calculated clock into the crtc state
  so that stuff that depends on it (eg. watermarks) will be
  calculated based on the actual hardware state we're going to use
  rather than the semi-fictional state we started with
- fix the fastset/fastboot stuff to actually require exact
  clock matches. Avoids the current mess where the user asks
  to slightly change the refresh rate (eg. to match video frame
  rate) but the kernel decides to ignore it and do a fastset instead.

v2: Repost of the remainder, earlier patches already merged

Ville Syrjälä (4):
  drm/i915: Split shared dpll .get_dplls() into compute and get phases
  drm/i915: Do .crtc_compute_clock() earlier
  drm/i915: Clean up DPLL related debugs
  drm/i915: Reassign DPLLs only for crtcs going throug .compute_config()
