Dear Andrew Lunn,

Right, that's true. I knew about this, but since the pinmux
configuration was made explicit for those GPIOs, I thought the original
author(s) of this .dts did this intentionally. For example, it somewhat
documents the 8 GPIOs that are available in the bottom connector of the
OpenBlocks A6. They are not tied to anyway particular device, so they
wouldn't appear anywhere in the DT. Ditto for the DIP switch GPIOs. Do
you also want those to be removed from the DT?

Thanks,

Thomas
