Description:

Specify a software pattern for the LED, that supports altering

the brightness for the specified duration with one software

timer. It can do gradual dimming and step change of brightness.

a pattern on high-resolution timer (hrtimer).

Red/Green/Blue/Amber (RGBA) color mixing applications. Each LED is
