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. |
