[PATCH v3 0/3] drm/msm/dpu: simplify dpu_hw_blk handling

[PATCH v3 0/3] drm/msm/dpu: simplify dpu_hw_blk handling

[Dmitry Baryshkov]

Drop most of "extra" features of dpu_hw_blk.

Changes since v2:
 - Include a patch to fix compilation issue with merge3d id handling

Changes since v1:
 - Make dpu_hw_blk an empty structure
 - Split this into separate patchset

----------------------------------------------------------------
Dmitry Baryshkov (4):
      drm/msm/dpu: remove unused dpu_hw_blk features
      drm/msm/dpu: drop dpu_hw_blk_destroy function
      drm/msm/dpu: use struct dpu_hw_merge_3d in dpu_hw_pingpong
      drm/msm/dpu: hw_blk: make dpu_hw_blk empty opaque structure

[PATCH v3 1/4] drm/msm/dpu: remove unused dpu_hw_blk features

[Dmitry Baryshkov]

Remove all unused dpu_hw_blk features and functions:
- dpu_hw_blk_get()/_put() and respective refcounting,
- global list of all dpu_hw_blk instances,
- dpu_hw_blk_ops and empty implementation inside each hw_blk subdriver.

This leaves dpu_hw_blk as a placeholder with just type and index.

[PATCH v3 3/4] drm/msm/dpu: use struct dpu_hw_merge_3d in dpu_hw_pingpong

[Dmitry Baryshkov]

Use struct dpu_hw_merge_3d pointer in struct dpu_hw_pingpong rather
than using struct dpu_hw_blk. This is the only user of dpu_hw_blk.id,
which will be cleaned in the next patch.

[PATCH v3 4/4] drm/msm/dpu: hw_blk: make dpu_hw_blk empty opaque structure

[Dmitry Baryshkov]

The code does not really use dpu_hw_blk fields, so drop them, making
dpu_hw_blk empty structure.
