Trying simple kernel module to handle AXI GPIO interrupt.
attached system-user.dtsi & kernel module source
Kernel module getting loaded, but irq handler not getting triggered.

You could try the UIO:
However, the AXI GPIO is covered here:

Thank You for the response.
The UIO option tried earlier and working fine. AXI GPIO interrupt is a very fast interrupt (every 125us).
Faced issues with UIO in handling fast interrupt.
So i don't want to use the UIO / Sysfs method for handling interrupt. So custom Kernel module was tried but interrupt was not getting fired in driver.
