+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.
