+description:
+  The MAX98363 is a SoundWire input Class D mono amplifier that
+  supports MIPI SoundWire v1.2-compatible digital interface for
+  audio and control data.
+  SoundWire peripheral device ID of MAX98363 is 0x3X019F836300
+  where X is the peripheral device unique ID decoded from pin.
+  It supports up to 10 peripheral devices(0x0 to 0x9).
