[PATCH v6 0/8] Introduce automatic DMA configuration for IOMMU masters

[Will Deacon]

Hello again,

This is version 6 of the patches previously posted here:

  RFCv1: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-August/283023.html
  RFCv2: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-September/283752.html
  RFCv3: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-September/287031.html
  RFCv4: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-November/302711.html
     v5: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-November/307213.html

The only change since v5 is the addition of acks from various maintainers.

Now that the ARM bits have rmk's ack and the IOMMU bits have joro's ack,
I think this is good for merging via the arm-soc tree.

Please let me know if a pull request would be preferable.

Cheers,

Will
