If not, and that patch is the offending commit, it probably means that the default routing table doesn't work for mt7623. Needs a specific soc table.
Hi Eric,
thanks for response, but it does not fix the issue for me. hdmi on mt7623 is DPI not DSI. There is already a mt7623 specific routing-table defined (one for DPI/HDMI and one for external=DSI/MIPI):

maybe it can be included or compared with the "default" route?
