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. | |
