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.
