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.



What:		/sys/bus/iio/devices/iio:deviceX/in_shunt_resistor

Date:		December 2015

KernelVersion:	4.4

Contact:	linux-iio@vger.kernel.org

Description:

		The value of the shunt resistor may be known only at runtime fom an

		eeprom content read by a client application. This attribute allows to

		set its value in ohms.
