The device tree is based on an initial version by Fabien Parent Based written against the MediaTek BSP kernel ([1]). It has been cleaned up, some features have been added (GPIO LEDs, ethernet), and some features removed (audio, camera, display and dual-role USB). Those features will be added back once the corresponding DT bindings and/or drivers become available in the upstream kernel.
