Similar comments like for the RZ/T2H EVB, e.g.

    led-3 {
            /* DSW18-7: ON, DSW18-8: OFF */
            gpios = <&pinctrl RZN2H_GPIO(31, 6) GPIO_ACTIVE_LOW>;
            color = <LED_COLOR_ID_GREEN>;
            function = LED_FUNCTION_DEBUG;
            function-enumerator = <4>;
    };

Shouldn't that be "DSW19-3: OFF, DSW19-4: ON"?
