They don't descibe hardware fully yet but it's enough to boot a system.
Some missing blocks:
1. PMC (Power Management Controller?)
2. Ethernet
3. Crypto
4. Thermal
Asus DTS is missing defining full NAND partitions layout and buttons.
Further changes will fill those gaps as soon as required bindings will
be found / tested / added.
