Hi Rob,
thanks for the review.

If it's fine I will send a v6 version without the of_get_timeout_sec function,
I hope it's fine for Jean-Christophe too, he asked me to add that function.

About the right way to handle this parameter,
obviously I was thinking that was a good idea to add this binding,
Even some maintainers have suggested that was a good idea.

Regards
