   > I also like the idea of unifying interfaces and reducing the need to repeat it across each sensor. But I worry if this is really a general sensor solution. Mainly since this introduces an intermediate buffering which may not be desired (due to space and added processing, in contrast to simply have the lower half write into the buffer passed by the caller). Maybe this buffer could optionally be disabled somehow.
   
   Seems like we could add an interface to register a buffer with the driver?  IIO has this internal interface:
