Help text

If you say yes here you get support for the ambient light sensor interface on National Semiconductor / TI LM3533 Lighting Power chips.

The sensor interface can be used to control the LEDs and backlights of the chip through defining five light zones and three sets of corresponding output-current values.

The driver provides raw and mean adc readings along with the current light zone through sysfs. A threshold event can be generated on zone changes. The ALS-control output values can be set per zone for the three current output channels.
