Hi Wolfram, Hi Arnd, Hi all,

the intention of this patch-set is to refactor the DMA support in
the Renesas SDHI driver in order to make it easier to add support
for using the SDHI hardware with different DMA implementations.

This is based on earlier work, posted as "[PATCH/RFC v3 0/6] mmc:
renesas_sdhi: add R-Car Gen-3 DMA support". It attempts to implement
the reworking of the driver proposed by Arnd[1] in his review of that
patch-set.

[1] http://www.spinics.net/lists/linux-mmc/msg38004.html

Unlike that patch-set this patch-set does not add support for
R-Car Gen-3 DMA. Rather it focuses on refactoring the code.
