    +Description
    +-----------
    +
    +This driver implements support for Maxim MAX31732.
    +
    +The MAX31732 is a multi-channel temperature sensor that monitors its
    +own temperature and the temperatures of up to four external diodeconnected
    +transistors. The device operates with 3.0V to 3.6V supply range
    +and consume TBDμA of current in standby mode of operation. Resistance
    +cancellation feature compensates for high series resistance between
    +circuit-board traces and the external thermal diode, while beta
    +compensation corrects for temperature-measurement errors due to lowbeta
    +sensing transistors.
    +
    +The MAX31732 offers two open-drain, active-low alarm outputs,
    +ALARM1 and ALARM2. When the measured temperature of a channel
    +crosses the respective primary over/under temperature threshold levels
    +ALARM1 asserts low and a status bit is set in the corresponding thermal
    +status registers. When the measured temperature of a channel crosses the
    +secondary over/under temperature threshold levels, ALARM2 asserts low
    +and a status bit is set in the corresponding thermal status registers.
    +
    +Temperature measurement range: from -64°C to 150°C
    +
    +Temperature Resolution: 12 Bits, ±0.0625°C
