The other main point with this binding are multiple endpoints per port. So you can have, say, a display controller, with single port, which has two endpoints going to two separate LCD panels. In physical level that would usually mean that the same pins from the display controller are connected to two panels. Most likely this would mean that only one panel can be used at a time, possibly with different settings (say, 16 RGB pins for one panel, 24 RGB pins for the other).
