[Resolved] Ath79 Reset button not working

[biangbiangmian]

I am on the latest master snapshot using a Comfast CF-E5. The reset button is supposed to be on GPIO17. I have an IRQ entry of gpio-ath79 17 on my system but when I press the button I can never see any response in the logs, and the device never responds to the key with either a reboot or firstboot. What can I check? It used to work on an older version.

cat /proc/interrupts

Here is the relevant portion of the DTS file

	keys {
		compatible = "gpio-keys";

		reset {
			label = "reset";
			linux,code = <KEY_RESTART>;
			gpios = <&gpio 17 GPIO_ACTIVE_LOW>;
		};
	};

I think it's hardware. The same firmware works on another device. GPIO17 never goes lo when pressing the button on the faulty device.
