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.
