I've now applied the driver to the togreg branch of iio.git.
Should get a pull request out to Greg in about 2 weeks time and it'll
probably be in linux-next a week after that.  I'm assuming all the device
tree changes will got through the at91 tree and arm-soc etc. 
Shout if you want me to take them through IIO.

Thanks,

Jonathan
