At this stage of the cycle (we're already at -rc7) we limit things to strictly regression fixes, and seems this has been broken for some time, so I think this will have to wait for v4.2. After addresing the comments, Maxime should queue this up for arm-soc so we can get it in early in the v4.2-rc cycle.
