[PATCH 0/4] drm: Add various helpers for simple drivers

[Noralf TrÃnnes]

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_simple_display_pipe_init()
  Plane, crtc and encoder are collapsed into one entity.
- drm_panel_connector_create()
  Create a simple connector for a panel.

Noralf TrÃnnes (4):
  drm/fb-cma-helper: Add function drm_fb_cma_create_with_funcs()
  drm: Make drm_encoder_helper_funcs optional
  drm: Add helper for simple display pipeline
  drm/panel: Add helper for simple panel connector
