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

intel_surf_alignment() in particular has devolved into
a complete mess. Redesign the code so that we can handle
alignment restrictions in a nicer. Also adjust alignment
for TGL+ to actually match the hardware requirements.

v2: Drop the per-plane vma stuff as it was borked
    Don't temporarily remove the 2MiB DPT alignment for UV on TGL

Ville Syrjälä (9):
  drm: Rename drm_plane_check_pixel_format() to drm_plane_has_format()
  drm: Export drm_plane_has_format()
  drm/i915: Introduce the plane->min_alignment() vfunc
  drm/i915: Introduce fb->min_alignment
  drm/i915: Split cursor alignment to per-platform vfuncs
  drm/i915: Split pre-skl platforms out from intel_surf_alignment()
  drm/i915: Move intel_surf_alignment() into skl_univerals_plane.c
  drm/i915: Update plane alignment requirements for TGL+
  drm/i915: Nuke the TGL+ chroma plane tile row alignment stuff
