Right, I wanted to do that, but the simple-panel bindings has power-supply
as required and I desperately wanted to be compatible in order to make use
of the simple-panel driver. That driver does require this entry, so I do
not see any way around it. Any advice for this situation?

I'll change that in v4.

Good thing you added the plural, I found s/lrud/rlud/ and s/ldvs/lvds/
Nice catch btw, thanks!
