Actually, it's up to the hardware designer to choose. On my board for instance,
this chip is driving an RGB LED, but it can really drive three independent LEDs
if you want.
I agree that the RGB case is quite common nowadays and currently not very well
managed by the LED subsystem. But I do not think that this is specific to this
driver.

Florian
