Merge tag 'bcm2835-for-3.15-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-rpi into next/dt

Merge "ARM: bcm2835: DT changes for 3.15" from Stephen Warren:

A variety of features are added to the bcm2835 device trees:
- ARM PMU, for perf_event
- DMA controller
- I2S controller

A few cleanups are applied to the DTs too.
