Hi Pavel 

So far, it has not made it onto the generic LED list. And the current
implementation is unlikely to go as far as using the generic LED
code. But i would like the binding to be compatible with it, so that
some time in the future it could be migrated to being part of the
generic LED code. But that would also require extensions to the
generic LED code to support hardware offload of triggers.
