Will do. Just to summarize here, the typical use case for this type of
thermocouple converter involves sample rates that are relatively high
compared to what the hwmon interface can support. The upcoming hrtimer
trigger will match up well with this to support fine-grained
periodic samples. I'll add this in the v2 cover latter.
