These patches (against v3.4-rc3) 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. The LEDs and backlights can be controlled directly, through PWM input, or by the on-chip ambient light sensor. 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 driver presents a character device (/dev/lm3533-als) which can be used to retrieve the current light zone or to poll for zone changes. Further details and specifications will soon be available from http://www.ti.com/product/lm3533 This work has been done on behalf of National Semiconductor / Texas Instruments.
