I'm having some trouble getting my GPIOs to behave as I'd like. I don't know if 
my overlay is causing problems, or something else (it's here: 
http://pastebin.com/JqE4emX3). But right now, I can't use sysfs to write a 
value to a GPIO:

# echo 115 > /sys/class/gpio/export
# echo out > /sys/class/gpio/gpio115/direction
# cat /sys/class/gpio/gpio115/value
0
# echo on > /sys/class/gpio/gpio115/value
bash: echo: write error: Invalid argument

This is true regardless of whether or not I load my overlay. My base dtb looks 
like this: http://pastebin.com/Wja7ZQRk

This stuff used to work, so I may just be overlooking something, but I'm not 
100% sure.
