Merge tag 'mvebu-soc-3.16' of git://git.infradead.org/linux-mvebu into next/soc

Merge "ARM: mvebu: SoC changes for v3.16" from Jason Cooper:

mvebu SoC changes for v3.16

 - Armada 375/38x coherency support
 - Armada 375/38x SMP support
 - mvebu PMSU and CPU reset support
 - Armada 370/XP cpuidle support
 - kirkwood remove platform init of audio device
 - small fixes and cleanup for new SoC (375/38x)

Note:
 - due to complex deps, cpuidle changes Acked by appropriate maintainer for
   going though arm-soc tree.
