Kernel driver max31790 ====================== Supported chips: * Maxim MAX31730 Prefix: 'max31730' Addresses scanned: 0x1c, 0x1d, 0x1e, 0x1f, 0x4c, 0x4d, 0x4e, 0x4f Datasheet: https://datasheets.maximintegrated.com/en/ds/MAX31730.pdf Author: Guenter Roeck <linux@roeck-us.net> Description ----------- This driver implements support for Maxim MAX31730. The MAX31730 temperature sensor monitors its own temperature and the temperatures of three external diode-connected transistors. The operating supply voltage is from 3.0V to 3.6V. Resistance cancellation compensates for high series resistance in circuit-board traces and the external thermal diode, while beta compensation corrects for temperature-measurement errors due to low-beta sensing transistors.
