Description:

What:  /sys/bus/iio/devices/iio:deviceX/label
KernelVersion: 5.8
Contact: linux-iio@vger.kernel.org
Description:
  Optional symbolic label for a device.
  This is useful for userspace to be able to better identify an
  individual device.

  The contents of the label are free-form, but there are some
  standardized uses:

  For proximity sensors which give the proximity (of a person) to
  a certain wlan or wwan antenna the following standardized labels
  are used:

  * "proximity-wifi"
  * "proximity-lte"
  * "proximity-wifi-lte"
  * "proximity-wifi-left"
  * "proximity-wifi-right"

  These are used to indicate to userspace that these proximity
  sensors may be used to tune transmit power to ensure that
  Specific Absorption Rate (SAR) limits are honored.
  The "-left" and "-right" labels are for devices with multiple
  antennas.

  In some laptops/tablets the standardized proximity sensor labels
  instead indicate proximity to a specific part of the device:

  * "proximity-palmrest" indicates proximity to the keyboard's palmrest
  * "proximity-palmrest-left" indicates proximity to the left part of the palmrest
  * "proximity-palmrest-right" indicates proximity to the right part of the palmrest
  * "proximity-lap" indicates the device is being used on someone's lap

  Note "proximity-lap" is special in that its value may be
  calculated by firmware from other sensor readings, rather then
  being a raw sensor reading.

  For accelerometers used in 2-in-1s with 360° (yoga-style) hinges,
  which have an accelerometer in both their base and their display,
  the following standardized labels are used:

  * "accel-base"
  * "accel-display"

  For devices where an accelerometer is housed in the swivel camera subassembly
  (for AR application), the following standardized label is used:

  * "accel-camera"

KernelVersion: 2.6.35
Contact: linux-iio@vger.kernel.org
Description:
  Some devices have internal clocks.  This parameter sets the
  resulting sampling frequency.  In many devices this
  parameter has an effect on input filters etc. rather than
  simply controlling when the input is sampled.  As this
  affects data ready triggers, hardware buffers and the sysfs
  direct access interfaces, it may be found in any of the
  relevant directories.  If it affects all of the above
  then it is to be found in the base device directory.

  The stm32-timer-trigger has the additional characteristic that
  a sampling_frequency of 0 is defined to stop sampling.

  Channels with 'i' and 'q' modifiers always exist in pairs and both
  channels refer to the same signal. The 'i' channel contains the in-phase
  component of the signal while the 'q' channel contains the quadrature
  component.

KernelVersion: 6.1
Contact: linux-iio@vger.kernel.org
Description:
  For differential channels, this an offset that is applied
  equally to both inputs. As the reading is of the difference
  between the two inputs, this should not be applied to the _raw
  reading by userspace (unlike _offset) and unlike calibbias
  it does not affect the differential value measured because
  the effect of _zeropoint cancels out across the two inputs
  that make up the differential pair. It's purpose is to bring
  the individual signals, before the differential is measured,
  within the measurement range of the device. The naming is
  chosen because if the separate inputs that make the
  differential pair are drawn on a graph in their
  _raw  units, this is the value that the zero point on the
  measurement axis represents. It is expressed with the
  same scaling as _raw.

Description:
  Adaptive thresholds are similar to normal fixed thresholds
  but the value is expressed as an offset from a value which
  provides a low frequency approximation of the channel itself.
  Thus these detect if a rapid change occurs in the specified
  direction which crosses tracking value + offset.
  Tracking value calculation is devices specific.

Description:
  When adaptive thresholds are used, the tracking signal
  may adjust too slowly to step changes in the raw signal.
  Thus these specify the time in seconds for which the
  difference between the slow tracking signal and the raw
  signal is allowed to remain out-of-range before a reset
  event occurs in which the tracking signal is made equal
  to the raw signal, allowing slow tracking to resume and the
  adaptive threshold event detection to function as expected.

Description:
  Specifies the hysteresis of threshold that the device is comparing

  If separate attributes exist for the two directions, but

  hysteresis value applies to both directions.

  For falling events the hysteresis is added to the _value attribute for
  this event to get the upper threshold for when the event goes back to
  normal, for rising events the hysteresis is subtracted from the _value
  attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200
  and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event
  will get activated once in_voltage0_raw goes above 1200 and will become
  deactivated again once the value falls below 1150.

KernelVersion: 2.6.37
Contact: linux-iio@vger.kernel.org
Description:
  Period of time (in seconds) for which the condition must be
  met before an event is generated. If direction is not
  specified then this period applies to both directions.

Description:
  If a low pass filter can be applied to the event generation
  this property gives its 3db frequency in Hz.
  A value of zero disables the filter.

Description:
  Enables or disables activity events. Depending on direction
  an event is generated when sensor ENTERS or LEAVES a given state.

Description:
  Confidence value (in units as percentage) to be used
  for deciding when an event should be generated. E.g for
  running: If the confidence value reported by the sensor
  is greater than in_activity_running_thresh_rising_value
  then the sensor ENTERS running state. Conversely, if the
  confidence value reported by the sensor is lower than
  in_activity_running_thresh_falling_value then the sensor
  is LEAVING running state.

Description:
  Similar to in_accel_x_thresh[_rising|_falling]_en, but here the

Description:
  Similar to in_accel_mag[_y][_rising|_falling]_en, but the event
  value is relative to a reference magnitude. The reference magnitude
  includes the graviational acceleration.
