+description: |
+  TSENSOR provides thermal and voltage sensors which monitor temperature
+  and voltage of the chip. Sensors are placed across the die to gauge the
+  temperature of the whole chip. The TSENSOR module:
+
+    Generates an interrupt to SW to lower temperature via DVFS on reaching
+    a certain thermal/voltage threshold.
+
+    Generates a signal to the CAR to reduce CPU frequency by half on reaching
+    a certain thermal/voltage threshold.
+
+    Generates a signal to the PMC when the temperature reaches dangerously high
+    levels to reset the chip and sets a flag in the PMC.
+
+  TSENSOR has two channels which monitor two different spots of the SoC.
