The XMOS XVF3500 VocalFusion Voice Processor[1] is a low-latency, 32-bit
multicore controller for voice processing.

Add new bindings to define the device properties.

This should be v2. Also, please provide changelog either here or in
cover letter.

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:
https://devicetree-specification.readthedocs.io/en/latest/chapter2-devicetree-basics.html#generic-names-recommendation

Previous version had different code here, so I don't understand why this
became model number.

That would also have saved me from giving a reference to a previous
discussion. In that case I will use v3 for the next version and the
previous series for the sound subsystem will be mentioned in the
changelog as v1.

Thanks for the reference, I will change it to the previous "voice-processor"

A USB device should hang off a USB hub (or root hub). Looks like you
just have a random node here. You should also have a $ref to
usb-device.yaml. You'll see you need a reg property for example.
