The end of the series is just a reposting of the fp16 stuff for gen4+.
The start of the series is new stuff to allow planes to dictate the
minimum cdclk, which is sometimes needed for downscaling or fp16
(and sometimes even for other pixel formats). Thanks to that new code
the fp16 tests should now pass on bxt/glk.

Ville Syrjälä (19):
  drm: Add drm_modeset_lock_assert_held()
  drm/atomic-helper: Make crtc helper funcs optional
  drm/i915: Remove pointless planes_changed=true assignment
  drm/i915: Replace is_planar_yuv_format() with
    drm_format_info_is_yuv_semiplanar()
  drm/i915: Allow downscale factor of <3.0 on glk+ for all formats
  drm/i915: Extract intel_modeset_calc_cdclk()
  drm/i915: s/pipe_config/crtc_state/ in intel_crtc_atomic_check()
  drm/i915: Stop using drm_atomic_helper_check_planes()
  drm/i915: Add debugs to distingiush a cd2x update from a full cdclk
    pll update
  drm/i915: Make .modeset_calc_cdclk() mandatory
  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
