+description: |
+  The controller provices USB2.0 compliant FullSpeed peripheral
+  implementation over the  SPI interface.
+
+  Specifications about the part can be found at:
+    http://datasheets.maximintegrated.com/en/ds/MAX3420E.pdf
+
+properties:
+  compatible:
+    enum:
+      - maxim,max3420-udc
+      - maxim,max3421-udc
+
+  reg:
+    maxItems: 1
+
+  interrupts:
+    minItems: 1
+    maxItems: 2
+    items:
+      - const: udc
+      - const: vbus
+
+  spi-max-frequency:
+    maximum: 26000000
+
+required:
+  - compatible
+  - reg
+  - interrupts
+  - interrupt-names
+
+examples:
+  - |
+      #include <dt-bindings/gpio/gpio.h>
+      #include <dt-bindings/interrupt-controller/irq.h>
+      spi0 {
