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.
