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.
