+description: |
+ The TI K3 family of SoCs typically have a Voltage & Thermal
+ Management (VTM) device to control up to 8 temperature diode
+ sensors to measure silicon junction temperatures from different
+ hotspots of the chip as well as provide temperature, interrupt
+ and alerting information.
+
+ The following polynomial equation can then be used to convert
+ value returned by this device into a temperature in Celsius
+
+ Temp(C) = (-9.2627e-12) * x^4 + (6.0373e-08) * x^3 + \
+ (-1.7058e-04) * x^2 + (3.2512e-01) * x + (-4.9003e+01)
