Mike,

I going to go ahead a take this through my tree.  I'll hold it off until
my last pull request for the merge window (I'm guessing about a week).
If you object, just let me know before then and I'll drop it.

Applied to mvebu/drivers for v3.13 and flagged for stable going back to
v3.11.  Also added Gregory's Ack.
