[PATCH 0/3] arm64: Default to non-coherent DMA ops

[catalin.marinas@arm.com (Catalin Marinas)]

Following recent discussions and patch from Ritesh, I'm planning to
align the default DMA ops with 32-bit arm and make them non-coherent. In
addition, we need to make sure that devices marked explicitly as
coherent use the correct dma ops. Until Santosh's DMA patches get
reviewed/merged, the temporary solution is bus notifiers which check the
"dma-coherent" property and set the right dma ops.

  arm64: Use bus notifiers to set per-device coherent DMA ops
  arm64: Mark the Applied Micro X-Gene SATA controller as DMA coherent

  arm64: Make default dma_ops to be noncoherent
