Thanks for this driver.

I have "another" 4xx-gpiolib driver version in my patch queue. It's also not 
polished yet. That's the reason why I didn't post it till now. I'll post my 
driver version in a short while. It's tested on a 405EP and an 440EPx system 
and "should" work on all other 4xx based platforms.

The community then can decide which driver version should be polished for 
upstream merge...

Best regards,
Stefan
