I've applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to play with it.  It also makes sense for me to
take the dts binding update as it goes with the driver change. 

Hence I've just left patch 4 for Kevin.  Doesn't matter if this crosses
with Kevin also taking patch 3 though as it'll get sorted out automatically
by git later anyway.

Thanks
