| Some devices have internal clocks. This parameter sets the |

| 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. |

| 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 |

| Description: |
| Event generated when channel passes a threshold on the rate of |
| change (1st differential) 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>_roc_value) or |
| <type>[Y][_name]_<raw|input>_roc_rising_value and |
| <type>[Y][_name]_<raw|input>_roc_falling_value may take |
| different values, but the device can only enable both rate of |
| change thresholds or neither. |
| Note the driver will assume the last p events requested are |
| to be enabled where p is however 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 a future point (and not those for |
| whatever event was previously enabled). |

| Description: |
| Specifies the hysteresis of threshold that the device is comparing |
| against for the events enabled by |
| <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. |
