[PATCH v3 0/5] drm/tinydrm: Use damage helper for dirtyfb

[Noralf Trønnes]

David discovered a bug which gave memory corruption because the tx_buf
was written past its end for st7586 which has a smaller tx_buf. The
problem was that mipi_dbi_enable_flush() now calls directly into
mipi_dbi_fb_dirty() instead of going via the tindyrm_device dirtyfb
callback.

Changes:
- Include vblank header (Sam)
- ili9225 and st7586 can't use mipi_dbi_enable_flush() (David)

Noralf.

Noralf Trønnes (5):
  drm/gem-fb-helper: Add drm_gem_fb_create_with_dirty()
  drm/damage-helper: Add drm_atomic_helper_damage_merged()
  drm/tinydrm: Use struct drm_rect
  drm/tinydrm: Use damage helper for dirtyfb
  drm/todo: Tick off some tinydrm entries
