Changes in v3:
- Readded disappeared YUV flag to PSEUDO_YUV_FMT_TILED
- Link to v2: https://lore.kernel.org/r/20250905-dpu-formats-v2-0-7a674028c048@oss.qualcomm.com

Changes in v2:
- Dropped DX flag from the tiled NV12 format structure (Jessica)
- Changed round_up(foo, 192) to the roundup() as the former one is
  supposed to be used with power of 2 argument (Jessica)
- Fixed undefined varuables warning in
  _dpu_format_populate_plane_sizes_ubwc() by dropping the always-true
  condition (LKP)
- Link to v1: https://lore.kernel.org/r/20250705-dpu-formats-v1-0-40f0bb31b8c8@oss.qualcomm.com

Dmitry Baryshkov (12):
      drm/msm/disp: set num_planes to 1 for interleaved YUV formats
      drm/msm/disp: set num_planes and fetch_mode in INTERLEAVED_RGB_FMT
      drm/msm/disp: set num_planes, fetch_mode and tile_height in INTERLEAVED_RGB_FMT_TILED
      drm/msm/disp: simplify RGB{,A,X} formats definitions
      drm/msm/disp: simplify tiled RGB{,A,X} formats definitions
      drm/msm/disp: pull in common YUV format parameters
      drm/msm/disp: pull in common tiled YUV format parameters
      drm/msm/disp: drop PSEUDO_YUV_FMT_LOOSE_TILED
      drm/msm/dpu: simplify _dpu_format_populate_plane_sizes_*
      drm/msm/dpu: drop redundant num_planes assignment in _dpu_format_populate_plane_sizes*()
      drm/msm/dpu: rewrite _dpu_format_populate_plane_sizes_ubwc()
      drm/msm/dpu: use standard functions in _dpu_format_populate_plane_sizes_ubwc()
