| 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 | |
| effects data ready triggers, hardware buffers and the sysfs | |
| direct access interfaces, it may be found in any of the | |
| relevant directories. If it effects all of the above | |
| then it is to be found in the base device directory. | |

| Description: | |
| Event generated when channel passes a threshold in the specified | |
| (_rising|_falling) direction. If the direction is not specified, | |
| then either the device will report an event which ever direction | |
| a single threshold value is passed in (e.g. | |
| <type>[Y][_name]_<raw|input>_thresh_value) or | |
| <type>[Y][_name]_<raw|input>_thresh_rising_value and | |
| <type>[Y][_name]_<raw|input>_thresh_falling_value may take | |
| different values, but the device can only enable both thresholds | |
| or neither. | |
| Note the driver will assume the last p events requested are | |
| to be enabled where p is how many it supports (which may vary | |
| depending on the exact set requested. So if you want to be | |
| sure you have set what you think you have, check the contents of | |
| these attributes after everything is configured. Drivers may | |
| have to buffer any parameters so that they are consistent when | |
| a given event type is enabled at a future point (and not those for | |

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

| <type>Y[_name]_thresh[_(rising|falling)]_hysteresis. | |
| If separate attributes exist for the two directions, but | |
| direction is not specified for this attribute, then a single | |
| 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 | |
| deactived again once the value falls below 1150. | |

| Description: | |
| Description of the scan element data storage within the buffer | |
| and hence the form in which it is read from user-space. | |
| Form is [be|le]:[s|u]bits/storagebits[>>shift]. | |
| be or le specifies big or little endian. s or u specifies if | |
| signed (2's complement) or unsigned. bits is the number of bits | |
| of data and storagebits is the space (after padding) that it | |
| occupies in the buffer. shift if specified, is the shift that | |
| needs to be applied prior to masking out unused bits. Some | |
| devices put their data in the middle of the transferred elements | |
| with additional information on both sides. Note that some | |
| devices will have additional information in the unused bits | |
| so to get a clean value, the bits value must be used to mask | |
| the buffer output value appropriately. The storagebits value | |
| also specifies the data alignment. So s48/64>>2 will be a | |
| signed 48 bit integer stored in a 64 bit location aligned to | |
| a 64 bit boundary. To obtain the clean value, shift right 2 | |
| and apply a mask to zero the top 16 bits of the result. | |
| For other storage combinations this attribute will be extended | |
| appropriately. | |

| E.g. for steps: the pedometer saves power while not used; | |
| when activated, it will count the steps taken by the user in | |
| firmware and export them through in_steps_input. | |
| What: /sys/.../iio:deviceX/in_steps_input | |
| KernelVersion: 3.19 | |
| Contact: linux-iio@vger.kernel.org | |
| Description: | |
| This attribute is used to read the number of steps taken by the user | |
| since the last reboot while activated. | |
| What: /sys/.../iio:deviceX/in_velocity_sqrt(x^2+y^2+z^2)_input | |
| What: /sys/.../iio:deviceX/in_velocity_sqrt(x^2+y^2+z^2)_raw | |
| KernelVersion: 3.19 | |
| Contact: linux-iio@vger.kernel.org | |
| Description: | |
| This attribute is used to read the current speed value of the | |
| user (which is the norm or magnitude of the velocity vector). | |
| Units after application of scale are m/s. | |
| What: /sys/.../iio:deviceX/in_steps_debounce_count | |
| KernelVersion: 4.0 | |
| Contact: linux-iio@vger.kernel.org | |
| Description: | |
| Specifies the number of steps that must occur within | |
| in_steps_filter_debounce_time for the pedometer to decide the | |
| consumer is making steps. | |
| What: /sys/.../iio:deviceX/in_steps_debounce_time | |
| KernelVersion: 4.0 | |
| Contact: linux-iio@vger.kernel.org | |
| Description: | |
| Specifies number of seconds in which we compute the steps | |
| that occur in order to decide if the consumer is making steps. | |
| What: /sys/bus/iio/devices/iio:deviceX/buffer/watermark | |
| KernelVersion: 4.2 | |
| Contact: linux-iio@vger.kernel.org | |
| Description: | |
| A single positive integer specifying the maximum number of scan | |
| elements to wait for. | |
| Poll will block until the watermark is reached. | |
| Blocking read will wait until the minimum between the requested | |
| read amount or the low water mark is available. | |
| Non-blocking read will retrieve the available samples from the | |
| buffer even if there are less samples then watermark level. This | |
| allows the application to block on poll with a timeout and read | |
| the available samples after the timeout expires and thus have a | |
| maximum delay guarantee. | |
| What: /sys/bus/iio/devices/iio:deviceX/buffer/hwfifo_enabled | |
| KernelVersion: 4.2 | |
| Contact: linux-iio@vger.kernel.org | |
| Description: | |
| A read-only boolean value that indicates if the hardware fifo is | |
| currently enabled or disabled. If the device does not have a | |
| hardware fifo this entry is not present. | |
| The hardware fifo is enabled when the buffer is enabled if the | |
| current hardware fifo watermark level is set and other current | |
| device settings allows it (e.g. if a trigger is set that samples | |
| data differently that the hardware fifo does then hardware fifo | |
| will not enabled). | |
| If the hardware fifo is enabled and the level of the hardware | |
| fifo reaches the hardware fifo watermark level the device will | |
| flush its hardware fifo to the device buffer. Doing a non | |
| blocking read on the device when no samples are present in the | |
| device buffer will also force a flush. | |
| When the hardware fifo is enabled there is no need to use a | |
| trigger to use buffer mode since the watermark settings | |
| guarantees that the hardware fifo is flushed to the device | |
| buffer. | |
| What: /sys/bus/iio/devices/iio:deviceX/buffer/hwfifo_watermark | |
| KernelVersion: 4.2 | |
| Contact: linux-iio@vger.kernel.org | |
| Description: | |
| Read-only entry that contains a single integer specifying the | |
| current watermark level for the hardware fifo. If the device | |
| does not have a hardware fifo this entry is not present. | |
| The watermark level for the hardware fifo is set by the driver | |
| based on the value set by the user in buffer/watermark but | |
| taking into account hardware limitations (e.g. most hardware | |
| buffers are limited to 32-64 samples, some hardware buffers | |
| watermarks are fixed or have minimum levels). A value of 0 | |
| means that the hardware watermark is unset. | |
| What: /sys/bus/iio/devices/iio:deviceX/buffer/hwfifo_watermark_min | |
| KernelVersion: 4.2 | |
| Contact: linux-iio@vger.kernel.org | |
| Description: | |
| A single positive integer specifying the minimum watermark level | |
| for the hardware fifo of this device. If the device does not | |
| have a hardware fifo this entry is not present. | |
| If the user sets buffer/watermark to a value less than this one, | |
| then the hardware watermark will remain unset. | |
| What: /sys/bus/iio/devices/iio:deviceX/buffer/hwfifo_watermark_max | |
| KernelVersion: 4.2 | |
| Contact: linux-iio@vger.kernel.org | |
| Description: | |
| A single positive integer specifying the maximum watermark level | |
| for the hardware fifo of this device. If the device does not | |
| have a hardware fifo this entry is not present. | |
| If the user sets buffer/watermark to a value greater than this | |
| one, then the hardware watermark will be capped at this value. | |
| What: /sys/bus/iio/devices/iio:deviceX/buffer/hwfifo_watermark_available | |
| KernelVersion: 4.2 | |
| Contact: linux-iio@vger.kernel.org | |
| Description: | |
| A list of positive integers specifying the available watermark | |
| levels for the hardware fifo. This entry is optional and if it | |
| is not present it means that all the values between | |
| hwfifo_watermark_min and hwfifo_watermark_max are supported. | |
| If the user sets buffer/watermark to a value greater than | |
| hwfifo_watermak_min but not equal to any of the values in this | |
| list, the driver will chose an appropriate value for the | |
| hardware fifo watermark level. |
