This LTDC port/endpoint stuff always scares me, because I always feel I
get it wrong.
I believe the LTDC does have one "port" , correct.
But I think (?) that the LTDC has two endpoints, endpoint@0 for DPI
(parallel output out of the SoC) and endpoint@1 for DSI (internal
connection into the DSI serializer) ?
Only one of the endpoints can be connected at a time, but there are
actually two endpoints in the LTDC port {} node, aren't there ?
So the original description should be OK I think , maybe
#address/#size-cells are missing instead ?
