drm: Add helper for simple display pipeline
Provides helper functions for drivers that have a simple display pipeline. Plane, crtc and encoder are collapsed into one entity. Changes since v4: - Remove drm_connector_register() call - Forgot to assign pipe->connector Changes since v3: - (struct drm_simple_display_pipe *)->funcs should be const Changes since v2: - Drop Kconfig knob DRM_KMS_HELPER - Expand documentation Changes since v1: - 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() Cc: jsarha@ti.com Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1465570559-14238-1-git-send-email-noralf@tronnes.org
