These patches (against v3.4-rc5) add support for the National Semiconductor /
Texas Instruments LM3533 lighting-power chip.
This multi-function device has four LEDs, two backlights and an
ambient-light-sensor interface.
The LEDs and backlights can be controlled directly, through PWM input,
or by the ambient-light-sensor interface. Hardware-accelerated blinking is
provided for the LEDs.
ALS control is done through defining five light zones and three sets of
corresponding brightness target levels. The ALS iio-driver provides raw and
mean adc readings along with the current light zone through sysfs. A threshold
event can be generated on zone changes.
Further details and specifications are now available from:
http://www.ti.com/product/lm3533
Changes since v1 includes a rewrite of the ambient-light-sensor driver against
iio, the addition of sysfs-ABI documentation, and a switch to regmap for
register io.
This work has been done on behalf of National Semiconductor / Texas
Instruments.
Thanks,
Johan
