Merge tag 'v3.17-next-mediatek-support' of https://github.com/mbgg/linux-mediatek into next/soc

Merge basic support for the Mediatek Cortex-A7 SoCs from Matthias Brugger:

Support is quite basic, as the only component working up to now are the
timers.

* tag 'v3.17-next-mediatek-support' of https://github.com/mbgg/linux-mediatek:
arm: mediatek: add dts for Aquaris5 mobile phone
dt-bindings: add documentation for Mediatek SoC
