CONFIG_MFD_LM3533
lm3533-als
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.
