[PATCH v2 4/4] drm/bridge: ti-sn65dsi86: Support hotplug detection

2022-03-07 Thread Kieran Bingham
When the SN65DSI86 is used in DisplayPort mode, its output is likely routed to a DisplayPort connector, which can benefit from hotplug detection. Support it in such cases, with polling mode only for now. The implementation is limited to the bridge operations, as the connector operations are
