  10 Description:    SoundWire Slave status
  11
  12                 These properties report the Slave status, e.g. if it
  13                 is UNATTACHED or not, and in the latter case show the
  14                 device_number. This status information is useful to
  15                 detect devices exposed by platform firmware but not
  16                 physically present on the bus, and conversely devices
  17                 not exposed in platform firmware but enumerated.
