Pull-up/down control via sysfs

[Gottfried Haider <gottfried.haider@xxxxxxxxx>]

Hello all,

I am interested in implementing a sysfs way to control pull-up/down
bias for gpio pins. I believe the pinctrl subsystem offers a pin
configuration interface [1] that my driver could implement for this,
but I am not sure about cross-referencing this from the gpio subsystem
and getting sysfs access..

Any hints/pointers would be greatly appreciated.

Thanks
Gottfried
