Bug ID: 256372
Summary: gpioctl fails to set input pull-up condition properly
Product: Base System
Version: 13.0-RELEASE
Hardware: arm64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: arm
Assignee: freebsd-***@FreeBSD.org
Reporter: ***@gmail.com

load SD card image on either a RPi4 or Pi 400
pick a GPIO pin e.g. 24
enter the following as root;

#gpioctl -l | grep 24

*/you will see the status of pin 24 usually defaults as an <IN>put with value 0
*/pin 24: 0 24<IN>


*/Let's set this input as Pulled-Up

#gpioctl -c 24 IN PU
#gpioctl -l | grep 24

*/you will see the configuration change to
*/pin 24: 0 24<IN,PU>
*/but the pin value of 0 should be 1 now, since it has been pulled-up

I verified that this is exclusive to the RPi 4 family only. Tested on a RPi3B+
and it works properly. Lastly, these are all certified Raspberry Pi products
not knock-offs.
