  1. What: /sys/bus/iio/devices/iio:deviceX/in_allow_async_readout
  2. Date: December 2015
  3. KernelVersion: 4.4
  4. Contact: linux-iio@vger.kernel.org
  5. Description:
  6. By default (value '0'), the capture thread checks for the Conversion
  7. Ready Flag to being set prior to committing a new value to the sample
  8. buffer. This synchronizes the in-chip conversion rate with the
  9. in-driver readout rate at the cost of an additional register read.
  10. Writing '1' will remove the polling for the Conversion Ready Flags to
  11. save the additional i2c transaction, which will improve the bandwidth
  12. available for reading data. However, samples can be occasionally skipped
  13. or repeated, depending on the beat between the capture and conversion
  14. rates.
  15. What: /sys/bus/iio/devices/iio:deviceX/in_shunt_resistor
  16. Date: December 2015
  17. KernelVersion: 4.4

  19. Description:
  20. The value of the shunt resistor may be known only at runtime fom an
  21. eeprom content read by a client application. This attribute allows to
  22. set its value in ohms.
