Subject: [PATCH v3 0/2] drm: Add various helpers for simple drivers

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

4 patches from the previous version have been applied and 2 are now left.

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 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()

Noralf Trønnes (2):
  drm/fb-cma-helper: Add function drm_fb_cma_create_with_funcs()
  drm: Add helper for simple display pipeline
