Hi, I'm using DE0-Nano-SoC, and I try to write a driver to handle interrupt from the push bottom. Any one knows which device tree file (.dts in arch/arm/boot/dts ) should I use for interrupt (push buttom)?

Hi,

 

You may want to create the device tree, there is a guide here on the creation of the device tree and with interrupts bindings:
