This is a well-structured 16-patch series by Thomas Zimmermann that converts all mipi-dbi based DRM drivers from the `drm_simple_display_pipe` abstraction to regular atomic modesetting helpers. The motivation is sound: simple-display-pipe helpers have been a source of confusion for new driver authors and add an unnecessary intermediate layer. The series is v3 with review from David Lechner (Acked-by on all patches).

The overall approach is clean:
1. Fix the commit-tail ordering so plane updates happen after CRTC enable (patch 1)
2. Factor out device init from pipeline init (patch 2)
3. Provide macro-based initializers for atomic helpers (patch 3)
4. Convert each driver individually (patches 4-14)
5. Remove the now-unused simple-display code from mipi-dbi (patch 15)
6. Deprecate simple-kms helpers project-wide (patch 16)

The conversion pattern is consistent and mechanical across all drivers. There are a few minor issues noted below, but nothing that would block merging. The series has already been acked by the relevant reviewer.
