IMX6UL redundant interrupts

I develop driver for Linux which need to count level changes on the line.

I register my ISR at falling trigger, but I see hadler called on rising level.

 

I attached some debug info as screenshots and minimal code I can reproduce the problem with.

Why is ISR called redundantly? Would appreciate any thoughts on this.
Thanks.
