+  SoundWire busses can be described with a node for the SoundWire controller
+  device and a set of child nodes for each SoundWire slave on the bus.

+        description: Is the textual representation of SoundWire Enumeration
+          address. compatible string should contain SoundWire Version ID,
+          Manufacturer ID, Part ID and Class ID in order and shall be in
+          lower-case hexadecimal with leading zeroes.
+          Valid sizes of these fields are
+          Version ID is 1 nibble, number '0x1' represents SoundWire 1.0
+          and '0x2' represents SoundWire 1.1 and so on.
+          MFD is 4 nibbles
+          PID is 4 nibbles
+          CID is 2 nibbles
+          More Information on detail of encoding of these fields can be
+          found in MIPI Alliance DisCo & SoundWire 1.0 Specifications.
