The order of endpoints in the ports is arbitrary. Each encoder with an associated input multiplexer has multiple input ports in the device tree. The order and reg property of the ports must correspond to the multiplexer input order. Since the imx-drm node now only needs to contain links to the display interfaces, it can be moved to the SoC dtsi level. At the board level, only connections between the display interface ports and encoders or panels have to be added.
