Hello,
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.
