Hi Stefan,

Assuming the DT binding is fine with the DT maintainers, I plan to
pick the pair of IIO fixes up through my tree.  Is there any strong
reason they should go via another route?

It's common for the dts files to go via ARM soc in cases like this
and we tend not to worry that they are 'broken' until the binding docs
are visible via other trees. Other than that I can't see an obvious
reason not to split these up.

Thanks,

Jonathan
