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

From: Noralf TrÃnnes
Date: Thu May 12 2016 - 14:25:49 EST


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()
