Merge branch 'for-v3.7' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping
Pull CMA and DMA-mapping updates from Marek Szyprowski:
"This time the pull request is rather small, because the further
redesign patches were not ready on time.
This pull request consists of the patches which extend ARM DMA-mapping
subsystem with support for CPU coherent (ACP) DMA busses. The first
client of the new version is HighBank SATA driver. The second part of
the pull request includes various cleanup for both CMA common code and
ARM DMA-mapping subsystem."
Fix up trivial add-add conflict due to the "dma-coherent" DT property
being added next to the "calxeda,port-phys" property for the Calxeda
AHCI controller.
* 'for-v3.7' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping:
ARM: dma-mapping: Remove unsed var at arm_coherent_iommu_unmap_page
ARM: highbank: add coherent DMA setup
ARM: kill off arch_is_coherent
ARM: add coherent iommu dma ops
ARM: add coherent dma ops
ARM: dma-mapping: Refrain noisy console message
ARM: dma-mapping: Small logical clean up
drivers: dma-contiguous: refactor dma_alloc_from_contiguous()
