@Rc.1 How did you manage to configure the pullup via the device tree? I have the problem that my GPIO muxings and additional settings are not that easily picked up and applied by the kernel. The only workaround I found so far involves writing a dumm...

I would also be interested in this. The only answer I found so far is writing a dummy driver existing solely, so we can declare something in the device tree and reference the pinctrl node for our GPIO. There has got to be a simpler solution.
