Hi,

Currently the gpio-keys schema allows any property to be present, even
undocumented.  Narrow the pattern for children to require specific key naming like:

    gpio-keys {
        compatible = "gpio-keys";

        // "up" is wrong
        key-up {
            label = "GPIO Key UP";
            linux,code = <103>;
            gpios = <&gpio1 0 1>;
        };
    };

This will cause many, many DTS warnings, which I can fix. But before I start
such big work, let's agree whether the approach is correct.

Best regards,
Krzysztof
