* usage pattern is that during either encoder module probe or DSI
* host attach, a drm_panel will be looked up through
* drm_of_find_panel_or_bridge(). drm_panel_bridge_add() is used to
* wrap that panel in the new bridge, and the result can then be
* passed to drm_bridge_attach(). The drm_panel_prepare() and related
* functions can be dropped from the encoder driver (they're now
* called by the KMS helpers before calling into the encoder), along
* with connector creation. When done with the bridge,
* drm_bridge_detach() should be called as normal, then
* drm_panel_bridge_remove() to free it.
