MIPI-DSI devices, if they are controlled through the bus itself, have to be described as a child node of the controller they are attached to. Thus, there's no requirement on the controller having an OF-Graph output port to model the data stream: it's assumed that it would go from the parent to the child. However, some bridges controlled through the DSI bus still require an input OF-Graph port, thus requiring a controller with an OF-Graph output port. This prevents those bridges from being used with the controllers that do not have one without any particular reason to. Let's drop that requirement.
