5 Description:
6 Event generated when channel passes one of the four thresholds
7 in each direction (rising|falling) and a zone change occurs.
8 The corresponding light zone can be read from
9 in_illuminance0_zone.

15 Description:
16 Get the hysteresis for thresholds Y, that is,
17 threshY_hysteresis = threshY_raising - threshY_falling

21 Date: April 2012
22 KernelVersion: 3.5
23 Contact: Johan Hovold <jhovold@gmail.com>
24 Description:
25 Specifies the value of threshold that the device is comparing
26 against for the events enabled by
27 in_illuminance0_thresh_either_en (0..255), where Y in 0..3.
28
29 Note that threshY_falling must be less than or equal to
30 threshY_raising.
31
32 These thresholds correspond to the eight zone-boundary
33 registers (boundaryY_{low,high}) and define the five light
34 zones.

40 Description:
41 Get the current light zone (0..4) as defined by the
42 in_illuminance0_threshY_{falling,rising} thresholds.

45 Date: May 2012
46 KernelVersion: 3.5
47 Contact: Johan Hovold <jhovold@gmail.com>
48 Description:
49 Set the output current for channel out_currentY when in zone
50 Z (0..255), where Y in 0..2 and Z in 0..4.
51
52 These values correspond to the ALS-mapper target registers for
53 ALS-mapper Y + 1.
54
55 Note that out_currentY_raw provides the current for the
56 current zone.
