No, DSI is shared without any switches in a "Y" connection.
I agree with Loic that not splitting that part but modifying it would be better.
My goal in doing that was to write as little as possible to allow a
bigger audience to play or repurpose DTSOs.
Since V2 has no panel I'll avoid splitting them anyway.
