pinctrl-bcm2835: Runtime configuration of pull-ups?

Hello all,

I understand that the pinctrl driver can enable the pins' internal
pull-ups (or pull-downs) based on device tree configuration. Are there
plans to expose this functionality to user-space, so that one could
dynamically enable or disable the pull-up of exported GPIO pins?

I haven't done any coding in the kernel before, but I would be happy
to give it a try, if its feasible for me to do, and relevant for other
people as well?
