+= SoundWire devices
+Each subnode of the bus represents SoundWire device attached to it.
+The properties of these nodes are defined by the individual bindings.
+
+= EXAMPLE
+The following example represents a SoundWire controller on DB845c board
+which has controller integrated inside WCD934x codec on SDM845 SoC.
