System key value registration failed，The reset button and WPS button of ZyXEL EX5700 are invalid. It feels like GPIO-KEYS is not registered.Is the driver missing or the GPIO is wrong?

DTS info：
gpio-keys {
compatible = "gpio-keys";
poll-interval = <20>;
reset-button {
label = "reset";
gpios = <&pio 9 GPIO_ACTIVE_LOW>;
linux,code = <KEY_RESTART>;
};

wps-button {
	label = "wps";
	gpios = <&pio 10 GPIO_ACTIVE_LOW>;
	linux,code = <KEY_WPS_BUTTON>;
};

};
