10 - Laxman Dewangan <ldewangan@nvidia.com>
13 On some of platforms, thermal sensor like thermistors are connected to
14 one of ADC channel and sensor resistance is read via voltage across the
15 sensor resistor. The voltage read across the sensor is mapped to
16 temperature using voltage-temperature lookup table.
