The version of these patches are restarted, as the previous drm_connector_oob_hotplug_event()-based approach was abandoned and this only barely resembles that effort. In this effort the HPD handling is based on the reliance of the hpd_notify() being invoked by a downstream (next_bridge) drm_bridge implementation, such as the standard display-connector, or a something like an USB Type-C controller implementation.
