| 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. |

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

| 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. |

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

| 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. |
| |
| Note that out_currentY_raw provides the current for the |
| current zone. |
