[MinnowBoard] GPIO pin mux state

[Holmberg, Hans]

>Anyone know how to set a GPIO pin mux state?

Yep. It's a bit obscure, but you can enable GPIOs via the LPSS configuration in the BIOS:

press F5 during boot
go to System setup > South cluster configuration > LPSS & SCC configuration 
Scroll down and disable the function that is set as primary configuration for the PIN you wish to use as a GPIO.

See http://elinux.org/Minnowboard:MinnowMax#Layout
Example: disabling PWM1 will let you use PIN 22 as a GPIO.

Best regards,
