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.

12 Date:           May 2012
13 KernelVersion:  3.5
14 Contact:        Johan Hovold <jhovold@gmail.com>
15 Description:
16                 Get the hysteresis for thresholds Y, that is,
17                 threshY_hysteresis = threshY_raising - threshY_falling

20 What:           /sys/.../events/illuminance_threshY_raising_value
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.

37 Date:           April 2012
38 KernelVersion:  3.5
39 Contact:        Johan Hovold <jhovold@gmail.com>
40 Description:
41                 Get the current light zone (0..4) as defined by the
42                 in_illuminance0_threshY_{falling,rising} thresholds.

44 What:           /sys/bus/iio/devices/iio:deviceX/out_currentY_currentZ_raw
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.
