Hi Daniel,

Please don't be so quick to send the next revision as soon as you
receive comments on a series - as has just been demonstrated, I've
replied to Rob's comment about moving the binding to clocks which
I don't agree with having read the documentation.

Posting a new series so quickly cuts off any hope of a sensible
discussion, and leads to people having to scramble to say "no,
we're still discussing the previous series" to possibly prevent
netdev applying the patches before the discussion has reached
a conclusion.

Thanks.
