What:		/sys/bus/iio/devices/iio:deviceX/fault_ovuv
KernelVersion:	5.11
Contact:	linux-iio@vger.kernel.org
Description:
		Overvoltage or Undervoltage Input fault. The internal circuitry
		is protected from excessive voltages applied to the thermocouple
		cables at FORCE+, FORCE2, RTDIN+ & RTDIN-. This circuitry turn
		off when the input voltage is negative or greater than VDD.

		Reading returns '1' if input voltage is negative or greater
		than VDD, otherwise '0'.

What:		/sys/bus/iio/devices/iio:deviceX/in_filter_notch_center_frequency
KernelVersion:	5.11
Contact:	linux-iio@vger.kernel.org
Description:
		Notch frequency in Hz for a noise rejection filter. Used i.e for
		line noise rejection.

		Valid notch filter values are 50 Hz and 60 Hz.
