If I got this right, the property does not enable dual-link operations by itself, but it needs the next bridge to be operating in dual link mode (ie. has both LVDS0 and LVDS1 output connected to its input ports). Is it worth describing it here (or at least clarify the the property alone does not enable dual link operations).
