2 KernelVersion:  5.11
3 Contact:        linux-iio@vger.kernel.org
4 Description:
5                 Overvoltage or Undervoltage Input fault. The internal circuitry
6                 is protected from excessive voltages applied to the thermocouple
7                 cables at FORCE+, FORCE2, RTDIN+ & RTDIN-. This circuitry turn
8                 off when the input voltage is negative or greater than VDD.
9
10                 Reading returns '1' if input voltage is negative or greater
11                 than VDD, otherwise '0'.
