Hello, I'm curious if there has been any further development towards
being able to control pull up or pull down through libgpiod.
Thanks,

I met with Drew yesterdat and we decided he will take a stab at fixing
this for the benefit of all Adafruits etc.

Awesome! Let me know if I can help. I'll make sure this gets supported
in libgpiod as soon as we have an interface exposed by the kernel.
