2016-07-31hwmon: (sht3x) set initial jiffies to last_updateMatt Ranostay1-1/+1
Handling the wraparound requires the data->last_update to be set to an initial jiffies value. Otherwise on 32-bit systems you will not be able to request a reading till the 5 minute jiffies rollover happens.

2016-06-27hwmon: add support for Sensirion SHT3x sensorsDavid Frey1-0/+725
This driver implements support for the Sensirion SHT3x-DIS chip, a humidity and temperature sensor. Temperature is measured in degrees celsius, relative humidity is expressed as a percentage. In the sysfs interface, all values are scaled by 1000, i.e. the value for 31.5 degrees celsius is 31500.
