We have this working on the 2708 based rasp-pi kernels by manually putting the device registration in the platform files. This change does things properly in a device tree. The boot messages look proper, but my rasp-pi hangs somewhere in USB enabling when running a stock 3.13-rc6 kernel so I have been unable to fully test this change. I also understand that the rasp-pi 1176 pmu support is missing the overflow interrupt. I'm not sure if that's true of all 2835 implementations. If not, then this patch will need to be changed a bit.
