Hi Daniel-

Thanks for your work on this, some of it looks very useful. I will go
through and review each patch in turn.

I have been working on Atmel's version of this driver. You can find most of
that work on our github site: as you know we are intending to push it
upstream as much as possible:
https://github.com/atmel-maxtouch

The main overlap between your changes and ours is in your approach to
writing config from userspace. There is a lot of complexity in these chips
and providing a sysfs node for each function would end up being a
never-ending task.

So we have implemented an interface using a sysfs binary attribute which I
think is considerably more general and flexible than the interface that you
suggest. You can find a set of utilities on the same github that uses our
interface. I would argue that we should try and converge the mainline
driver on our approach rather than inventing something new unless there are
significant advantages.

cheers
