| 10 | If you say yes here you get support for the ambient light sensor |
| 11 | interface on National Semiconductor / TI LM3533 Lighting Power |
| 12 | chips. |
| 13 | |
| 14 | The sensor interface can be used to control the LEDs and backlights |
| 15 | of the chip through defining five light zones and three sets of |
| 16 | corresponding output-current values. |
| 17 | |
| 18 | The driver provides raw and mean adc readings along with the current |
| 19 | light zone through sysfs. A threshold event can be generated on zone |
| 20 | changes. The ALS-control output values can be set per zone for the |
| 21 | three current output channels. |
