dt-bindings: arm: mediatek: mmsys: Add OF graph support for board path
Document OF graph on MMSYS/VDOSYS: this supports up to three DDP paths
per HW instance (so potentially up to six displays for multi-vdo SoCs).
The MMSYS or VDOSYS is always the first component in the DDP pipeline,
so it only supports an output port with multiple endpoints - where each
endpoint defines the starting point for one of the (currently three)
possible hardware paths.
