Several patches have been pushed, new patches have appeared at the end.
I wonder if I've invented a perpetual motion patch series...

The new stuff is mostly just cleaning up the cdclk state (mis)management
we have going on. I also modifier the global state locking stuff
a bit to make sure we correctly serialize the hardware stuff when
cdclk actually changes (and we need it for the QGV stuff as well).

I also tweaked the debug messages to trigger only when a plane
actually needs to bump the cdclk. Previously it would print that
stuff all the time.

Ville Syrjälä (13):
  drm/i915: Add debugs to distingiush a cd2x update from a full cdclk
    pll update
  drm/i915: Rework global state locking
  drm/i915: Move check_digital_port_conflicts() earier
  drm/i915: Allow planes to declare their minimum acceptable cdclk
  drm/i915: Eliminate skl_check_pipe_max_pixel_rate()
  drm/i915: Simplify skl_max_scale()
  drm/i915: Add support for half float framebuffers for skl+
  drm/i915: Add support for half float framebuffers for gen4+ primary
    planes
  drm/i915: Add support for half float framebuffers for ivb+ sprites
  drm/i915: Add support for half float framebuffers on snb sprites
  drm/i915: Move more cdclk state handling into
    intel_modeset_calc_cdclk()
  drm/i915: Consolidate more cdclk state handling
  drm/i915: Collect more cdclk state under the same roof
