Hi Wolfram,

I've rebased the set of patches on 3.7-rc6. I hope you could apply them.

Regards

Ludovic

Changes:
- v3
    - introduce two new patches: one to fix a compilation warning and one to
    fix indentation
    - introduce a threshold to use dma transfers
    - use dma wrappers to clean code
    - remove dma cookie since it is no more used

- v2 (based on Russell feedback):
    - replace DMA_TO_DEVICE/DMA_FROM_DEVICE by DMA_MEM_TO_DEV/DMA_DEV_TO_MEM
    - don't check for tx_submit errors
    - atmel dma header location has changed
