Subject: [PATCH 0/4] mfd: add LM3533 lighting-power chip driver

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.

Thanks,
Johan
