AW: How do I set user space GPIO polarity (active state) via device tree?

Hello,

I am still not able to declare the polarity of a GPIO via device tree
so it can be used from user space using libgpio.

I read the kernel documentation and did not find hint how to do this.
What I found is how to set the polarity of a GPIO for a gpio-hog or a
kernel driver. But that prevents the GPIO being used from user space.

Thank you in advance for your help,
