If you say yes here you get support for the Avago ADJD-S311-CR999
|
|
digital color light sensor.
|
|
|
|
This driver can also be built as a module. If so, the module
|
|
will be called adjd_s311.

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.

Say Y here if you want to build a driver for the Vishay VCNL4000
|
|
combined ambient light and proximity sensor.
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called vcnl4000.
