/**
* \defgroup rgb-led Generic RGB LED driver
*
* This is a driver for a tri-color RGB LED part, such as for example the
* Broadcom (ex Avago Technologies) PLCC-4 Tricolor Black Surface LED present
* on all Zolertia Zoul-based boards.
*
*
* This driver sits on top of the LED HAL. Therefore, any port that wishes to
* use this driver should first implement the GPIO HAL and the new LED API.
* This driver will set the colour of the RGB LED by using combinations of
* LED_RED, LED_GREEN and LED_BLUE. Therefore, those must be correctly defined
* by the platform configuration.
* @{
