Supported chips:
* Maxim MAX31730
Prefix: 'max31730'
Addresses scanned: 0x1c, 0x1d, 0x1e, 0x1f, 0x4c, 0x4d, 0x4e, 0x4f

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.
