            Bug ID: 224512
           Summary: new device ID for nctgpio (APU3)
           Product: Base System
           Version: 11.1-STABLE
          Hardware: amd64
                OS: Any
            Status: New

patch against driver source

The PCEngines APU3 has a new gpio chip that is not recognized by the existi=
ng
driver due to a new ID.  The attached simple diff provides GPIO functionali=
ty
to the APU3 and FreeBSD.
