Andreas Dannenberg 94a9b7b180 iio: light: add support for TI's opt3001 light sensor
TI's opt3001 light sensor is a simple and yet powerful
little device. The device provides 99% IR rejection,
automatic full-scale, very low power consumption and
measurements from 0.01 to 83k lux.

This patch adds support for that device using the IIO
framework.

See http://www.ti.com/product/opt3001 for more information.

Gabriele Mazzotta feca56ff40 iio: acpi: Add support for ACPI0008 Ambient Light Sensor
This driver adds the initial support for the ACPI Ambient Light Sensor
as defined in Section 9.2 of the ACPI specification (Revision 5.0) [1].

Sensors complying with the standard are exposed as ACPI devices with
ACPI0008 as hardware ID and provide standard methods by which the OS
can query properties of the ambient light environment the system is
currently operating in.

This driver currently allows only to get the current ambient light
illuminance reading through the _ALI method, but is ready to be
extended extended to handle _ALC, _ALT and _ALP as well.

than just appending new entries at the end, since it reduces the amount of

Johan Hovold 9c8ea1b29b iio: add LM3533 ambient-light-sensor driver
Add sub-driver 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.
