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.
