- Description: SoundWire Slave status
- These properties report the Slave status, e.g. if it
- is UNATTACHED or not, and in the latter case show the
- device_number. This status information is useful to
- detect devices exposed by platform firmware but not
- physically present on the bus, and conversely devices
- not exposed in platform firmware but enumerated.
