NXP pca9532 is a LED dimmer/controller attached to i2c bus.
It allows attaching upto 16 leds which can either be on, off
or dimmed and/or blinked with the two PWM modulators available.
This driver is a "new-style" i2c driver that adheres to the
driver model and implements the led framework api. Since the
leds connected to driver are platform specific, it is only
usefull when platform data is passed to the driver to define
what leds are connected to which pins.
