>Description:
The BeagleBone Black permits to set an input GPIO pin
as pull-up or pull-down. This is very useful
at the moment of using the BBB to interface with 
external circuits. 

gpioctl(8) does not permit setting the "pu","pd" flags
which control the connection of on-board pull-up and pull-down resistors.


>How-To-Repeat:

---- rc.conf ---
gpio=yes
----------------

---- gpio.conf ---
gpio1 17 set in pd
------------------

#> reboot 

---- dmesg ----------
...
Checking quotas: done.
Configuring GPIO.
gpioctl: GPIOSET: Operation not supported by device
...
