+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.
