Eric put a lot of time and effort into naming the GPIO lines on the
other Pi board.

So please follow the good example and name the GPIO lines on this board
like in the other rpi boards, should be something like:

&pio {
    gpio-line-names = "...", "...";
};

This is very helpful for users.

Yours,
