It seems basically the same as my patch (gpio driver for
mpc831x/mpc834x/mpc837x with OF bindings) from September 5th except
you don't have any documentation and the Kconfig doesn't depend on
831x/834x/837x.

Galak, did you have time to look at these patches yet?

Why do you need this when you have the lock?
