Some boards use these to control their backlight or a few LEDs. There's supposed to be 4 of them, but the fourth one has a different configuration register scheme, and I couldn't find any board that was using this GPIO. It will be probably be supported eventually, but until then, we support only the first 3 GPIOs.
