description:
  i.MX91 features a new temperature sensor. It includes programmable
  temperature threshold comparators for both normal and privileged
  accesses and allows a programmable measurement frequency for the
  Periodic One-Shot Measurement mode. Additionally, it provides
  status registers for indicating the end of measurement and threshold
  violation events.
