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()
