Updates of SoC-near drivers and other driver updates that makes more sense to
take through our tree. In this case it's involved:
- Some Davinci driver updates that has required corresponding platform code
changes (gpio mostly)
- CCI bindings and a few driver updates
- Marvell mvebu patches for PCI MSI support (could have gone through the PCI
tree for this release, but they were acked by Bjorn for 3.12 so we kept them
through arm-soc).
- Marvell dove switch-over to DT-based PCIe configuration
- Misc updates for Samsung platform dmaengine drivers
