the current interface is very low-level, while the proposal
from Pavel/John has a much different scope, imho.

I'm working on a led driver for the ixp4xx/NSLU2 which
has 2 leds plus a multi-coloured one.

We would benefit a lot from such an implementation so,
FWIW, I express my personal support and the one
of the whole nslu2-linux community.

Once this patch is upstream, the linux-arm interface could easily
be adapted to use it or cooperate nicely.
