This is looking great!

I assume you will merge this through the ARM SoC tree and the
PrimaII branch? Tell me if you need it to be merged through the
pinctrl tree.

As noted you can use pinconf-generic and friends, but it's definately
not a requirement. You can also do that as a refactoring on top of this
