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. -Matt > >Matt Porter (3): > > iio: temperature: add max6675 dt binding > > iio: temperature: add max6675 thermocouple converter driver > > MAINTAINERS: add max6675 driver > > > > .../bindings/iio/temperature/max6675.txt | 19 +++ > > MAINTAINERS | 7 + > > drivers/iio/temperature/Kconfig | 11 ++ > > drivers/iio/temperature/Makefile | 1 + > >drivers/iio/temperature/max6675.c | 155 > >+++++++++++++++++++++ > > 5 files changed, 193 insertions(+) > >create mode 100644 > >Documentation/devicetree/bindings/iio/temperature/max6675.txt > > create mode 100644 drivers/iio/temperature/max6675.c > > -- > Sent from my Android device with K-9 Mail.
