Device metadata field (device_def::meta)
I2C: device connected through the IIC protocol

The function defines the functionality that the device is designated to
serve. Lunaix identify the following values:
TTY: a device which can be called as teletypewriter, system can use such
device for output into external environment
+
+ CFG: device that provide configuration service to the system or other
+ devices
