[PATCH v4 0/3] drm: Add various helpers for simple drivers

Show all headers | View raw

This patchset adds various helpers that was originally part of the
tinydrm patchset.

Essentially it adds 2 functions:
- drm_fb_cma_create_with_funcs()
  CMA backed framebuffer supporting a dirty() callback.
- drm_simple_display_pipe_init()
  Plane, crtc and encoder are collapsed into one entity.


Changes since v3:
- Add patch 'drm/fb-cma-helper: Use const for drm_framebuffer_funcs argument'
- drm/fb-cma-helper: Add function drm_fb_cma_create_with_funcs()
  - funcs argument should be const
- drm: Add helper for simple display pipeline
  - (struct drm_simple_display_pipe *)->funcs should be const

Changes since v2:
- drm: Add helper for simple display pipeline
  - Drop Kconfig knob DRM_KMS_HELPER
  - Expand documentation

Changes since v1:
- Drop patch: drm/panel: Add helper for simple panel connector
- Add fb-helper and fb-cma-helper doc patches
- Add drm/atomic: Don't skip drm_bridge_*() calls if !drm_encoder_helper_funcs
- Add drm_atomic_helper_best_encoder()
- drm/fb-cma-helper: Add function drm_fb_cma_create_with_funcs()
  - Expand docs
- drm: Add helper for simple display pipeline
  - Add DOC header and add to gpu.tmpl
  - Fix docs: @funcs is optional, "negative error code",
    "This hook is optional."
  - Add checks to drm_simple_kms_plane_atomic_check()
