There's a choice about using the userland i2c stuff to access the
storage for the program or having a driver at all. If we have a driver,
we probably make a /sys you dump the LED state machine binary "program"
down to set it. That's probably as far as we should take it if even
What would guide us towards having a driver is if kernelside could want
to use the LEDs itself, eg, to indicate panic.
Another aspect suggesting we need a driver is trying to integrate the
LED actions and colours / programs with led class stuff like triggers.
