This has raced against Matti's series
https://lore.kernel.org/linux-iio/cover.1744022065.git.mazziesaccount@gmail.com/
Support ROHM BD79104 ADC

With hindsight that wasn't obvious from the patch series name though
which should ideally have been
iio: adc: ti-adc128s052: Support ROHM BD79104 ADC

Please rebase on the iio testing branch on kernel.org or on top of that series.
Technically I've only applied the first 7 patches so far, but the 8th
should be a simple change from that v3.
 
Matti, you volunteered as maintainer :)  Hence please take a look at
this one.

One nice thing in there is we now have a __be16 buffer16 element that
can avoid at least one cast in patch 2.

Thanks,

Jonathan
