How to configure a gpio pin to put imx6slevk in standby mode?

I'm using imx6slevk board with yocto bsp kernel version 4.9.88.


I want to configure a gpio pin(power button) to send the board to stand-by mode.

I'm able to enter stand by mode using echo "freeze" > /sys/power/state

and on pressing the power button the board wakes up


However the board doesn't go into standby on pressing the power button.

This is my dts node:


gpio-keys {
compatible = "gpio-keys";
power {
label = "Power Button";
gpios = <&gpio4 3 1>;
linux,code = <116>; // KEY_POWER
debounce-interval = <1>;
status = "okay";

like  gpio-key,wakeup; I tried adding gpio-key,sleep but it had no effect

is there any way I can configure this?
