Thanks. It was that part of the code that I spent the bulk of my time on.
And although it is still has a few rough edges I would be happy for it
to be used.

I would prefer to avoid requiring kernel changes unless necessary -
the kernels some of the boards I work with require DT since 3.5.
However, I am happy to discuss this further, there certainly is
merit to a clean implementation.
