[PATCH/RFC v2 5/5] mmc: renesas_sdhi: add support for R-Car Gen3 SDHI DMAC

2016-06-29 Thread Simon Horman
From: Yoshihiro Shimoda R-Car Gen3 has a dedicated DMA controller for SDHI module. Since the DMAC is in a part of SDHI module and is not suitable as dmaengine, this patch adds a different code as tmio_mmc_dma_gen3.c. Signed-off-by: Yoshihiro Shimoda
