Subject: [PATCH v2 0/6] drm: Add various helpers for simple drivers

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

Essentially it adds 3 functions:
- drm_fb_cma_create_with_funcs()
  CMA backed framebuffer supporting a dirty() callback.
- drm_atomic_helper_best_encoder()
  (struct drm_connector_helper_funcs *)->best_encoder callback helper.
- drm_simple_display_pipe_init()
  Plane, crtc and encoder are collapsed into one entity.

Plus it has gained a couple of documentation patches since v1.

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 (6):
  drm/fb-helper: Remove mention of CONFIG_FB_DEFERRED_IO in docs
  drm/fb-cma-helper: Hook up to DocBook and fix some docs
  drm/fb-cma-helper: Add function drm_fb_cma_create_with_funcs()
  drm/atomic: Don't skip drm_bridge_*() calls if
    !drm_encoder_helper_funcs
  drm/atomic: Add drm_atomic_helper_best_encoder()
  drm: Add helper for simple display pipeline
