A little while ago I wrote my own GPIO driver for the Au1000, mainly as
a learning experience. I never bothered to release it because a driver
already exists and I thought it was working. I'm not sure if it will
work on the Au1550, but if you're interested you can find the source

Thanks. Can't I just mmap /dev/mem and use the
GPIO offset from SYS_BASE?

little clueless as to how it is meant to be used. Can I use the GPIO
ioctl's from a userland program, or must I write a kernel module?
I'll see if I can dig up some docs and the example
userland program this weekend. That driver hasn't been
tested in a while though.
