+description: |
+  The Analog Devices MAX31732 is a local plus four-channel remote temperature
+  sensor that exposes two ALARM outputs, programmable limits and calibration
+  aids. The driver reports readings through the Linux hwmon subsystem and can
+  optionally use the ALARM pins as interrupts.
