+
+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.
+
+properties:
+  compatible:
+    enum:
+      - adi,max98363
+
+  reg:
+    maxItems: 1
+    description: Peripheral-device unique ID decoded from pin
+
+  vdd-supply:
+    description:
+      A 2.5V to 5.5V supply that powers up the VDD pin.
+
+  dvddio-supply:
+    description:
+      A 1.7V or 1.9V supply that powers up the DVDDIO pin.
+      This property is only needed for MAX98363A/B.
+
+required:
+  - compatible
+  - reg
+  - vdd-supply
+  - dvddio-supply
