Subject: [PATCH 3/3] ARM: dts: sun8i: add FriendlyARM NanoPi Duo2-IoT Box

The IoT-Box is a dock for the NanoPi Duo2, adding two USB host ports, a
10/100 ethernet port, a variety of pin headers for i2c and uarts, and a
quad band 2G GSM module, a SIM800C.

Full documentation and schematics available from vendor:
