I can consider that only if there is a real interest for it and would
love some help by the netdev team to actually have a review from the
leds team...

I tried multiple time to propose it but I never got a review... only a
review from an external guy that wanted to follow his idea in every way
possible with the only intention of applying his code (sorry to be rude
about that but i'm more than happy to recover the work and search for a
common solution)

So yes this is still in my TODO list but it would help if others can
tell me that they want to actually review it. That would put that
project on priority and I would recover and push a v7.
