From: Ludovic Barre <ludovic.barre@st.com> The goal of this serie is to add support of sdmmc for stm32. 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 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 (24): mmc: mmci: Change struct members from bool to u8 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 | 616 +++++++++++++++++-------- drivers/mmc/host/mmci.h | 186 ++++++-- drivers/mmc/host/mmci_qcom_dml.c | 16 +- drivers/mmc/host/mmci_stm32_sdmmc.c | 282 +++++++++++ 7 files changed, 904 insertions(+), 218 deletions(-) create mode 100644 drivers/mmc/host/mmci_stm32_sdmmc.c
