hwmon: Driver for NTC Thermistors
Add support for NTC Thermistor series. In this release, the following thermistors are supported: NCP15WB473, NCP18WB473, NCP03WB473, and NCP15WL333. This driver is based on the datasheet of MURATA. The driver in the patch does conversion from the raw ADC value (either voltage or resistence) to temperature. In order to use voltage values as input, the circuit schematics should be provided with the platform data. A compensation table for each type of thermistor is provided for the conversion.
