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

Gilad.

Hello,

I am trying to use the au1000_gpio driver, but I'm a
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.
