Be to able to add this new variant it is needed to do some changes in mmci core: -Internalize specific needs of legacy dmaengine. -Create and setup dma_priv pointer. -Create generic callbacks which share some features (like cookie...) and call specific needs. change v6: -move mmci_variant_init in mmci.c -dma_setup/release: let the variants clean up themselves. change v5: -error management in mmci_dmae_setup and qcom_dma_setup mmci_dmae_setup: fail when tx & rx are not defined. qcom_dma_setup: faill if one of channels is not defined. -define mmci_variant_init following CONFIG_DMA_ENGINE state. -squash dma_setup/dma_release callback. change v4: -checkpatch fix bool to u8 -add use_dma variable to fallback to pio mode -move to optional reset with dt binding note for sdmmc -separate patch for DT doc change v3: -remove __dma_inprogress rename -remove bad space at end of "st,use-ckin" change v2: -rename to mmci_prep/unprep_data -rename specific dma engine structure to mmci_dmae_next/priv -follow "_" recommandation -remove dma prefixe of mmci_dmae_priv fields Ludovic Barre (23): mmc: mmci: create common mmci_dma_setup/release mmc: mmci: introduce dma_priv pointer to mmci_host mmc: mmci: merge prepare data functions mmc: mmci: add prepare/unprepare_data callbacks mmc: mmci: add get_next_data callback mmc: mmci: add dma_start callback mmc: mmci: add dma_finalize callback mmc: mmci: add dma_error callback mmc: mmci: add validate_data callback mmc: mmci: add set_clk/pwrreg callbacks mmc: mmci: add datactrl block size variant property mmc: mmci: expand startbiterr to irqmask and error check mmc: mmci: add variant properties to define cpsm & cmdresp bits mmc: mmci: add variant property to define dpsm bit mmc: mmci: add variant property to define irq pio mask mmc: mmci: add variant property to write datactrl before command mmc: mmci: add variant property to not read datacnt dt-bindings: mmci: add optional reset property mmc: mmci: add optional reset property mmc: mmci: add clock divider for stm32 sdmmc mmc: mmci: add stm32 sdmmc registers dt-bindings: mmci: add stm32 sdmmc variant mmc: mmci: add stm32 sdmmc variant Documentation/devicetree/bindings/mmc/mmci.txt | 11 + drivers/mmc/host/Kconfig | 10 + drivers/mmc/host/Makefile | 1 + drivers/mmc/host/mmci.c | 628 ++++++++++++++++++------- drivers/mmc/host/mmci.h | 140 +++++- drivers/mmc/host/mmci_qcom_dml.c | 17 +- drivers/mmc/host/mmci_stm32_sdmmc.c | 282 +++++++++++ 7 files changed, 886 insertions(+), 203 deletions(-) create mode 100644 drivers/mmc/host/mmci_stm32_sdmmc.c -- 2.7.4
