imx6qdl - can a pair of GPIOs be implemented as a relay liked activity with Lollipop 5.0?

I would like to use two GPIO pins on the imx6qdl-sabrelite board to implement some relay liked activity.

That is one pin as an input, the other pin as output. Once the input pin becomes active, I would like to invert it and output to the output pin.


Can this be implemented with the existing device tree without needing a new driver on the kernel?
