+description: |
+  Generic MIDI interface using a serial device. Can only be set to use standard speeds
+  corresponding to supported baud rates of the underlying serial device. If standard MIDI
+  speed of 31.25 kBaud is needed, configure the clocks of the underlying serial device
+  so that a requested speed of 38.4 kBaud resuts in the standard MIDI baud rate.
+
+properties:
+  compatible:
+    const: serialmidi
+
+  speed:
+    maxItems: 1
+    description: |
+      Speed to set the serial port to when the MIDI device is opened.
+      If not specified, the underlying serial device is allowed to use its configured default speed.
+
+required:
+  - compatible
+
+additionalProperties: false

+examples:
+  - |
+    serial {
+        midi {
+            compatible = "serialmidi";
+            speed = <38400>;
+        };
