In linux kernel since version 3.1 (release Date: 2011-10-24)  
This option enables support for the LEDs on National Semiconductor /
TI LM3533 Lighting Power chips.

The LEDs can be controlled directly, through PWM input, or by the
ambient-light-sensor interface. The chip supports
hardware-accelerated blinking with maximum on and off periods of 9.8
and 77 seconds respectively.
