I don't want to have combo start picking up IMUs so we need to be a bit careful. We could take the approach we have done with proximity and light sensors of effectively declaring one type to the dominant one. There it's a bit clearer though - you don't buy a proximity sensor if you want to just measure light levels. Here there isn't always a dominant type. The example here is titled input / output device so no preference of one over the other. The GPIO stuff is kind of a feature bolted on, so ADDAC is generic enough. For the ad7293 it does call it a Power Amplifiers 'with' the other stuff so maybe just sticking to amplifier as the type is the way to go. Meh, to a certain extent it doesn't matter - we can safely move these around once we have more of them in the tree. The adt7316 is still in staging and is an ADDAC as well so I think we should put that category in for now. Jonathan > >
