I'd like to take this for 4.3 on top of my current queue of ARM perf
updates. I've put together a branch, but it's not clear which tree this
should go through.

Russell: would you be ok taking this via the ARM tree, or would you
prefer it if I sent this via arm-soc? Personally, I think it makes sense
to send it to you along with the usual updates, but I appreciate you
don't normally touch drivers/ directly like this.
