   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

  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.

  48 Description:
  49                 Get output current for channel Y (0..255), that is,
  50                 out_currentY_currentZ_raw, where Z is the current zone.

  56 Description:
  57                 Set the output current for channel out_currentY when in zone
  58                 Z (0..255), where Y in 0..2 and Z in 0..4.
  59
  60                 These values correspond to the ALS-mapper target registers for
