Actually... the three LEDs are packaged such as this is one colorful
light to the user, right? Some day we'll need to group them, so that
kernel can automatically tell this is one led, and probably add extra
attributes, such as values that produce white light.

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.

Best regards,
Florian
