staging:iio:documentation pull a few sysfs entries out of main docs. 



These two attributes are only used in the one driver.  Whilst they
are fairly general I'm not entirely happy committing to them at
this stage.

Description:

		This attribute is used to read the amount of quadrature error

		present in the device at a given time.
 


What:		/sys/.../iio:deviceX/ac_excitation_en

KernelVersion:	3.1.0

Description:

		This attribute, if available, is used to enable the AC

		excitation mode found on some converters. In ac excitation mode,

		the polarity of the excitation voltage is reversed on

		alternate cycles, to eliminate DC errors.

Description:

		This attribute, if available, is used to close or open the

		bridge power down switch found on some converters.

		In bridge applications, such as strain gauges and load cells,

		the bridge itself consumes the majority of the current in the

		system. To minimize the current consumption of the system,

		the bridge can be disconnected (when it is not being used

		using the bridge_switch_en attribute.
