As this is just an ID and a bit of descriptive text, I'm not going to
waste Rob's time by expecting him to take a look!
@Rob: Of course you are welcome to take a look if you like.

I've tweaked the description a tiny bit as below.

Series applied to the togreg branch of iio.git and pushed out as testing
for all the normal reasons (autobuilders etc).

Thanks,

Jonathan

The Depending.... depending is a bit awkward so I'll rephrase that as

Some parts support higher MSPS and some lower MSPS, suitable for the
intended application of each part.
