[PATCH v6 2/5] hwmon: (core) Add support for humidity min/max alarm

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add min_alarm and max_alarm attributes for humidityX to support devices
that can generate these alarms.
Such attributes already exist for other magnitudes such as tempX.

Tested with a ChipCap 2 temperature-humidity sensor.
