[Power Button on OrangePi Lite not responding to ACPI events]

I am using OrangePi Lite with Armbian 21.02.3 (5.10.21-sunxi) and the power button is not responding to acpi events.

 

I have followed suggestions here but nothing works:

Here is my debugging process:

 

root@orangepilite:~# evtest
No device specified, trying to scan all of /dev/input/event*
Available devices:
/dev/input/event0:      r_gpio_keys
/dev/input/event1:      sunxi-ir
Select the device event number [0-1]: 0
Input driver version is 1.0.1
Input device ID: bus 0x19 vendor 0x1 product 0x1 version 0x100
Input device name: "r_gpio_keys"
Supported events:
  Event type 0 (EV_SYN)
  Event type 1 (EV_KEY)
    Event code 256 (BTN_0)
Properties:
Testing ... (interrupt to exit)

then pressing power key:

Event: time 1618068887.287759, type 1 (EV_KEY), code 256 (BTN_0), value 1
Event: time 1618068887.287759, -------------- SYN_REPORT ------------
Event: time 1618068887.463763, type 1 (EV_KEY), code 256 (BTN_0), value 0
Event: time 1618068887.463763, -------------- SYN_REPORT ------------

 

 

value on this line (currently at 15) increments when pressing power button:

watch cat /proc/interrupts
131:         15          0          0          0  sunxi_pio_edge   3 Edge      sw4

 

 

Pressing power key when running this command shows no result:

acpi_listen

 

I've tried installing archive image (Armbian 19.11.3 - kernel 5.3.9) but same issue.

 

Not sure if I need to enable `gpio-sunxi` module (found somewhere this may need to enable?) but both current and archive image says: "Module gpio-sunxi not found".

 

Which Armbian image version should I use to have this working? Or any module i need to install?
