Subject: [PATCH 0/4] axi-dmac: Add support for scatter-gather transfers

Hi Vinod,

This patchset updates the dma-axi-dmac driver, and introduces the
ability to use scatter-gather transfers, that are now supported by the
IP core.

When using an older version of the core, the driver will simply fall
back to using standard transfers.

The patchset was generated on top of today's linux-next (629a3b49f3f9).

Cheers,
-Paul
