  What:		/sys/.../events/in_illuminance0_thresh_either_en
  Date:		April 2012
  KernelVersion:	3.5
  Contact:	Johan Hovold <jhovold@gmail.com>
  Description:
  		Event generated when channel passes one of the four thresholds
  		in each direction (rising|falling) and a zone change occurs.
  		The corresponding light zone can be read from
  		in_illuminance0_zone.
  
  What:		/sys/.../events/in_illuminance0_threshY_hysteresis
  Date:		May 2012
  KernelVersion:	3.5
  Contact:	Johan Hovold <jhovold@gmail.com>
  Description:
  		Get the hysteresis for thresholds Y, that is,
  		threshY_hysteresis = threshY_raising - threshY_falling
  
  What:		/sys/.../events/illuminance_threshY_falling_value
  What:		/sys/.../events/illuminance_threshY_raising_value
  Date:		April 2012
  KernelVersion:	3.5
  Contact:	Johan Hovold <jhovold@gmail.com>
  Description:
  		Specifies the value of threshold that the device is comparing
  		against for the events enabled by
  		in_illuminance0_thresh_either_en (0..255), where Y in 0..3.
  
  		Note that threshY_falling must be less than or equal to
  		threshY_raising.
  
  		These thresholds correspond to the eight zone-boundary
  		registers (boundaryY_{low,high}) and define the five light
  		zones.
  
  What:		/sys/bus/iio/devices/iio:deviceX/in_illuminance0_zone
  Date:		April 2012
  KernelVersion:	3.5
  Contact:	Johan Hovold <jhovold@gmail.com>
  Description:
  		Get the current light zone (0..4) as defined by the
  		in_illuminance0_threshY_{falling,rising} thresholds.
  
  What:		/sys/bus/iio/devices/iio:deviceX/out_currentY_raw
  Date:		May 2012
  KernelVersion:	3.5
  Contact:	Johan Hovold <jhovold@gmail.com>
  Description:
  		Get output current for channel Y (0..255), that is,
  		out_currentY_currentZ_raw, where Z is the current zone.
  
  What:		/sys/bus/iio/devices/iio:deviceX/out_currentY_currentZ_raw
  Date:		May 2012
  KernelVersion:	3.5
  Contact:	Johan Hovold <jhovold@gmail.com>
  Description:
  		Set the output current for channel out_currentY when in zone
  		Z (0..255), where Y in 0..2 and Z in 0..4.
  
  		These values correspond to the ALS-mapper target registers for
  		ALS-mapper Y + 1.
