[PATCH v7 00/32] drm/msm/dpu: wide planes support

[Dmitry Baryshkov]

This patchset brings in multirect usage to support using two SSPP
rectangles for a single plane. Full virtual planes support is omitted
from this pull request, it will come later (I'm at the final stages of
polishing and testing, will be posted today).

Changes since v6:
- Really fixed line width check for UBWC formats (Abhinav)
- Also dropped R0/R1/R_MAX previously used by
  dpu_plane_validate_multirect_v2()
- Explicitly enabled SmartDMA for SC7280 following Abhinav's testing
- Reapplied Abhinav's Tested-by tags with the # sc7280 comment

Changes since v5:
- Rephrased wide planes commit message
- Fixed line width check for UBWC formats (Abhinav)
- Also drop struct dpu_multirect_plane_states, unused now

Changes since v4:
- Incorporate two fixes and two cleanup patches from Abhinav

Changes since v3:

- moved if (!pipe->sspp) checks back to the calling site, the caller
  should know if there is a backing SSPP or not.
- Restored state_idx argument of trace_dpu_crtc_setup_mixer trace point
- Removed .smart_dma_rev from dpu_caps
- Added cleaning of multirect to _dpu_plane_atomic_disable()
- Per Abhinavs request split the SmartDMA enablement patch into the
  "verified by me" and "the rest of the platforms" patches, which is not
  supposed to be merged in. Users of other platforms are supposed to
  verify multirect support on their platforms and then send patches
  enabling SmartDMA for their SoC.
- Expanded several commit messages

Changes since v2:

- Renamed dpu_hw_pipe_cfg to dpu_hw_sspp_cfg
- Added a patch to clean up src add / layout for the solid fill planes
- Fixed several comments and commit messages which caused confusion
- Added documentation for new dpu_plane_state members
- Slightly reworked dpu_plane_atomic_check() to make it more logical and obvious.

Changes since v1 (which was ages ago):
- Rebased on top of 6.2-rc1
- Dropped the controversial _dpu_crtc_blend_setup() split patch
- Renamed dpu_hw_pipe to dpu_hw_sspp
- Other misc changes
