DMA support for the SDHI driver has also been modified on a prototype level. Written to show how to make use of platform devices for DMA support until the DT bindings for the DMA hardware have been stabilized. Not for upstream merge. Depends on the following public SDHI patches by Morimoto-san: [PATCH] mmc: block: add block number limitation flag for lultiple block read [PATCH] mmc: sdhi: tidyup mmc_data setting for R-Car SDHI [PATCH] mmc: tmio: care about DMA tx/rx addr offset Signed-off-by: Magnus Damm --- Written on top of renesas-devel-v3.15-20140609v3 arch/arm/mach-shmobile/board-koelsch-reference.c | 154 +++++++++++++++++++++ arch/arm/mach-shmobile/board-lager-reference.c | 155 +++++++++++++++++++++- drivers/dma/sh/shdma.h | 4 drivers/dma/sh/shdmac.c | 48 +++++- drivers/mmc/host/sh_mobile_sdhi.c | 1 include/linux/mmc/sh_mobile_sdhi.h | 1 include/linux/sh_dma.h | 2 7 files changed, 355 insertions(+), 10 deletions(-)
