[PATCH v4 00/13] drm/msm/dpu: support virtual wide planes

[Dmitry Baryshkov]

As promised in the basic wide planes support ([1]) here comes a series
supporting 2*max_linewidth for all the planes.

Note: Unlike v1 and v2 this series finally includes support for
additional planes - having more planes than the number of SSPP blocks.

Note: this iteration features handling of rotation and reflection of the
wide plane. However rot90 is still not tested: it is enabled on sc7280
and it only supports UBWC (tiled) framebuffers, it was quite low on my
priority list.

Changes since v3:
- Dropped the drm_atomic_helper_check_plane_noscale (Ville)
- Reworked the scaling factor according to global value and then check
  if SSPP has scaler_blk later on.
- Split drm_rect_fp_to_int from the rotation-related fix (Abhinav)

Changes since v2:
- Dropped the encoder-related parts, leave all resource allocation as is
  (Abhinav)
- Significantly reworked the SSPP allocation code
- Added debugging code to dump RM state in dri/N/state

Changes since v1:
- Fixed build error due to me missing one of fixups, it was left
  uncommitted.
- Implementated proper handling of wide plane rotation & reflection.

Dmitry Baryshkov (13):
  drm/msm/dpu: take plane rotation into account for wide planes
  drm/msm/dpu: use drm_rect_fp_to_int()
  drm/msm/dpu: move pstate->pipe initialization to
    dpu_plane_atomic_check
  drm/msm/dpu: drop virt_formats from SSPP subblock configuration
  drm/msm/dpu: move scaling limitations out of the hw_catalog
  drm/msm/dpu: split dpu_plane_atomic_check()
  drm/msm/dpu: move rot90 checking to dpu_plane_atomic_check_pipe()
  drm/msm/dpu: add support for virtual planes
  drm/msm/dpu: allow using two SSPP blocks for a single plane
  drm/msm/dpu: allow sharing SSPP between planes
  drm/msm/dpu: create additional virtual planes
  drm/msm/dpu: allow sharing of blending stages
  drm/msm/dpu: include SSPP allocation state into the dumped state
