+ If separate attributes exist for the two directions, but
+ direction is not specified for this attribute, then a single

+ 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

+ 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.
