+description: |
+  Axiado AX3000 USB Device Controller (UDC) is used on
+  AX3000 SoCs and evaluation boards. This controller is based on a
+  Corigine USB IP core and provides SuperSpeed (5 Gb/s), High-Speed
+  (480 Mb/s). It supports control, bulk, interrupt, and isochronous
+  transfer types across multiple configurable endpoints. The node
+  describes the memory-mapped register region, interrupt line, and
+  other required properties for the UDC hardware.

Drop last sentence, completely redundant. There is no point to explain
what the binding or DT are.

-gen2

in such case, but I don't like these names. They are awfully
non-hardware looking.
