[ CCed Laurent Pinchart ] The renesas and shmobile portions of this seem reasonable to me and I have checked that there do not seem to be any conflicts with changes I already have queued up for v3.16 (and v3.17). I have CCed Laurent Pinchart as I believe he most recently did work on the renesas and shmobile code in question.
