Might be easier. I'll define Ax<n> as > 16 bit address for the burst read.

Probably not as a bus, it sounds like a marshalling difference rather than a bus - the buses should really only understand byte streams. I don't have any bright ideas on how to deal with this, it's fairly far away from the problem space I'm worried about. -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
