There are other bridges and panels which support both DSI burst and <br>
sync-pulse/sync-events modes, so a property which selects the mode is <br>
generic, not specific to this particular bridge . The bridge driver <br>
could parse such generic property, although it would be better if the <br>

Can you share which panel model this is ?<br>
