+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.
