I only did what needed to be done and I'm looking forward to you taking over 
shortly ;-)

No, noone did and I'd be really happy if you took this one.

I guess we'd need one more quick patch for current mainline then, since this 
seems to be broken ever since. I will bake one shortly.

Also, let me add two more goals:
- Migrate to driver model
- Support probing of the whole board from Device Tree Blob

This would make our lives so much easier, so we should aim for this. I don't 
know if it is realistic to make this happen for 2015.01, but I would like to
keep this in mind.
