* Setup fbdev emulation by calling drm_fb_helper_fbdev_setup() and tear it
* down by calling drm_fb_helper_fbdev_teardown().
*
- * Drivers that need to handle connector hotplugging (e.g. dp mst) can't use
- * the setup helper and will need to do the whole four-step setup process with
- * drm_fb_helper_prepare(), drm_fb_helper_init(),
- * drm_fb_helper_single_add_all_connectors(), enable hotplugging and
- * drm_fb_helper_initial_config() to avoid a possible race window.
- *
* At runtime drivers should restore the fbdev console by using
* drm_fb_helper_lastclose() as their &drm_driver.lastclose callback.
* They should also notify the fb helper code from updates to the output
* encoders and connectors. To finish up the fbdev helper initialization, the
* drm_fb_helper_init() function is called. To probe for all attached displays
* and set up an initial configuration using the detected hardware, drivers
- * should call drm_fb_helper_single_add_all_connectors() followed by
- * drm_fb_helper_initial_config().
+ * should call drm_fb_helper_initial_config().
*
* If &drm_framebuffer_funcs.dirty is set, the
* drm_fb_helper_{cfb,sys}_{write,fillrect,copyarea,imageblit} functions will
* deferred I/O (coupled with drm_fb_helper_fbdev_teardown()).
