Hello Jean, hello Hans, here is the tmp421 driver. It supports TI's TMP421/422/423 chips. I've tested the driver with Hans' great welcome gift, the tiny-usb-adapter. Further I played a bit with the dump to test remote sensors, extended temperature range, etc. Thanks, Andre --- Documentation/hwmon/tmp421 | 36 ++++ drivers/hwmon/Kconfig | 10 + drivers/hwmon/Makefile | 1 drivers/hwmon/tmp421.c | 331 +++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 378 insertions(+)
