The mmci host driver implementation for double buffering is not intended nor ready for mainline yet. It is only an example of how to implement pre_req() and post_req(). The reason for this is that the basic DMA support for MMCI is not complete yet. This patch series depends on "[PATCH 0/5] mmc: add double buffering for mmc block requests" Linus Walleij (1): mmci: add PrimeCell generic DMA to MMCI/PL180 Per Forlin (1): ARM: mmci: add support for double buffering Ulf Hansson (2): mmci: fixup broken_blockend variant patch MMCI: Corrections for DMA drivers/mmc/host/mmci.c | 538 ++++++++++++++++++++++++++++++++++++++------- drivers/mmc/host/mmci.h | 21 ++- include/linux/amba/mmci.h | 16 ++ 3 files changed, 496 insertions(+), 79 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
