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.
