The XMOS XVF3500 VocalFusion Voice Processor[1] is a low-latency, 32-bit multicore controller for voice processing. This device requires two power supplies and a specific power sequence to reach normal operation, where it registers itself as a USB device. These constraints cannot be cleanly solved without the use of a driver that guarantees proper initialization during system power-up sequences and sleep-mode transitions. Once in normal operation, the device works like a regular USB device with the obvious limitation that it cannot be unplugged because of its onboard nature. This series adds support for the XMOS XVF3500 and includes the device bindings, which also required a new entry in vendor-prefixes for the XMOS manufacturer.
