WTH: Why isn´t there GPIO support for ASUS tinkerboard?

So i wanted to make a simple cpu fan control in home assistant and found out that i can´t do it. There is no asus_gpio support. I really hope that there is someone who could add this feature.

Closing this. See About the Month of "What the heck?!" (2020), point 3:
