I can add an element (or elements) to the subdevice info structure -- that's not a problem. However, it is unclear how to precisely define one or several settling time parameters, since every manufacturer does this differently. The best I can come up with is "worst case settling time for full scale step to +/- 1 LSB while changing between channels with the same gain". I can find a numer of reasons why this is inadequate, but I suppose it's better than nothing. dave...
