I want to clean up the messy interactions between
cdclk/bw/dbuf/etc. code. Start to making the state
handling during readout/sanitation a bit more sane.

v2: Rebase due to intel_display changes
    Rework the intel_bw_crtc_update() stuff a bit (Vinod)

Ville Syrjälä (18):
  drm/i915: Drop redundant shared_dpll=NULL assignments
  drm/i915: Don't clobber crtc_state->cpu_transcoder for inactive crtcs
  drm/i915: Use intel_plane_set_invisible() in
    intel_plane_disable_noatomic()
  drm/i915: Extract intel_cdclk_crtc_disable_noatomic()
  drm/i915: Extract skl_wm_crtc_disable_noatomic()
  drm/i915: clean up pipe's ddb usage in intel_crtc_disable_noatomic()
  drm/i915: Add skl_wm_plane_disable_noatomic()
  drm/i915: Extract intel_bw_crtc_disable_noatomic()
  drm/i915: Extract intel_cdclk_update_hw_state()
  drm/i915: Extract intel_bw_update_hw_state()
  drm/i915: Update bw_state->active_pipes during readout
  drm/i915: Skip some bw_state readout on pre-icl
  sem/i915: Simplify intel_cdclk_update_hw_state()
  drm/i915: Simplify cdclk_disable_noatomic()
  drm/i915: Split wm sanitize from readout
  drm/i915: Do wm readout ealier for skl+
  drm/i915: Move dbuf_state->active_piepes into skl_wm_get_hw_state()
  drm/i915: Relocate intel_bw_crtc_update()
