+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.

+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.

+Date:		May 2012

+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.

+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.
