0010 Description: SoundWire Slave status
0011
0012 These properties report the Slave status, e.g. if it
0013 is UNATTACHED or not, and in the latter case show the
0014 device_number. This status information is useful to
0015 detect devices exposed by platform firmware but not
0016 physically present on the bus, and conversely devices
0017 not exposed in platform firmware but enumerated.
