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