Hi everyone,

As part of Google Summer of Code, I've tasked myself with implementing
DMA support for the earlier Allwinner platforms. This third round of
patches is the result of said effort.

The first patch is the actual driver to support these platforms. Patches
three, four and five add the corresponding DMA node to the sun4i, sun5i
and sun7i device trees.

The second patch, involving the sunxi SPI driver, lets users do SPI
transfers of >=64 bytes by using DMA. Patches six, seven and eight add
the DMA properties to SPI so the first two patches can be used.

All comments and reviews are welcome :)

Thanks!

Emilio
