2KernelVersion:
3Contact:	linux-iio@vger.kernel.org
4Description:
5		This attribute, if available, is used to enable the AC
6		excitation mode found on some converters. In ac excitation mode,
7		the polarity of the excitation voltage is reversed on
8		alternate cycles, to eliminate DC errors.

12Contact:	linux-iio@vger.kernel.org
13Description:
14		This attribute, if available, is used to close or open the
15		bridge power down switch found on some converters.
16		In bridge applications, such as strain gauges and load cells,
17		the bridge itself consumes the majority of the current in the
18		system. To minimize the current consumption of the system,
19		the bridge can be disconnected (when it is not being used
20		using the bridge_switch_en attribute.

23KernelVersion:
24Contact:	linux-iio@vger.kernel.org
25Description:
26		Initiates the system calibration procedure. This is done on a
27		single channel at a time. Write '1' to start the calibration.

37KernelVersion:
38Contact:	linux-iio@vger.kernel.org
39Description:
40		Reading returns a list with the possible calibration modes.
41		There are two available options:
42		"zero_scale" - calibrate to zero scale
43		"full_scale" - calibrate to full scale

46KernelVersion:
47Contact:	linux-iio@vger.kernel.org
48Description:
49		Sets up the calibration mode used in the system calibration
50		procedure. Reading returns the current calibration mode.
51		Writing sets the system calibration mode.
