Looks like the panel-enabled variants would better be described as device-tree overlays as they are not specific devices but are peripheral extensions. What do you think?

I don't agree. The Lichee RV 86 Panel is sold as a complete unit, with the SoM+board and LCD pre-assembled inside a case. It is not possible to purchase the board without a panel, so the panel-enabled variants are the only variants. Regards, Samuel

So yeah if it's an individual device on its own I agree it deserves its own dedicated device-tree. Cheers, Paul
