How to use dts or other setup to declare gpio pin Interrupt (e.g. a button)?
Using armbian bionic mainline kernel on A64-v1.1 board
Linux pine64 4.19.38-sunxi64 #5.83 SMP Fri May 3 21:02:31 CEST 2019 aarch64 aarch64 aarch64 GNU/Linux

In RPI bionic could just set values in boot.txt.  Is this possible in armbian bionic mainline?

I know that one can use device tree overlays but can't find any examples specific to the A64.

Anyone have a dts file or otherwise know how to declare a pin as an interruptible input?  I've come across nothing in any A64 docs.
Looks like I tracked down an example dts file here

here is more explanation of how to implment

Still need to edit, compile and try it, but at least good example to go from
