Matteo Martelli d3abae8c1e iio: ABI: generalize shunt_resistor attribute
Move ABI documentation for custom shunt resistor attributes into the
generic iio documentation file. Exception for pac1934: leave it
untouched since it does not comply with common iio ABI generalization.

What: /sys/bus/iio/devices/iio:deviceX/in_allow_async_readout Date: December 2015 KernelVersion: 4.4 Contact: linux-iio@vger.kernel.org Description: By default (value '0'), the capture thread checks for the Conversion Ready Flag to being set prior to committing a new value to the sample buffer. This synchronizes the in-chip conversion rate with the in-driver readout rate at the cost of an additional register read.

	Writing '1' will remove the polling for the Conversion Ready Flags to
	save the additional i2c transaction, which will improve the bandwidth
	available for reading data. However, samples can be occasionally skipped
	or repeated, depending on the beat between the capture and conversion
	rates.
