gpioctl should be able to switch pull-ups on if available. #20
Description
As discussed at brgl/libgpiod#31 (comment) , libgpiod cannot currently do it, and it's arguably out of scope for a generic GPIO library until there is a generic universal kernel interface for this. But if we detect a Raspberry Pi, it would be a nice move to optionally set the pull-ups or at least bundle a tool to do it.
