Virtual GPIO emulation

Does exist a virtual GPIO driver to be used for a programming needs?

I have to develop a software on my Linux PC, and then try it on some embedded systems with physical GPIOs (C.H.I.P., OpenWRT, and so on...)?

Thank you!

The solution exists and is available since kernel 4.10 as GPIO mockup driver.
