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.
