From: Ludovic Barre <ludovic.barre@xxxxxx> This patch serie adds support of stm32 SDMMC controller. stm32h7 is the first SoC to use stm32 SDMMC controller (previous SoC had pl180 controller). The SDMMC features include the following: -Full compliance with MultiMediaCard System Specification Version 4.51. Card support for three different databus modes: 1-bit (default), 4-bit and 8-bit. -Full compliance with SD memory card specifications version 4.1. SDR104 speed limited to maximum allowed I/O speed, SPI mode and UHS-II mode not supported. -Full compliance with SDIO card specification version 4.0. change V2: -dt-bindings: properties name st,dir-output-high; st,neg-edge; st,use-ckin -dt-bindings: node example s/sdmmc@/mmc@/g -removes return of enable/disable_imask functions -adds dev_warn if clk divisor is too short. -replaces overprotection of n_elem by fail of dma_map_sg -removes shortcut host->base -Use device_property_present Ludovic Barre (5): dt-bindings: mmc: document the stm32 sdmmc bindings mmc: add stm32 sdmmc controller driver ARM: dts: stm32: add sdmmc support for stm32h743 ARM: dts: stm32: add sdmmc1 support for stm32h743i-eval ARM: configs: stm32: add mmc and ext2/3/4 support .../devicetree/bindings/mmc/st,stm32-sdmmc.txt | 35 + arch/arm/boot/dts/stm32h743-pinctrl.dtsi | 26 + arch/arm/boot/dts/stm32h743.dtsi | 26 + arch/arm/boot/dts/stm32h743i-eval.dts | 11 + arch/arm/configs/stm32_defconfig | 4 +- drivers/mmc/host/Kconfig | 8 + drivers/mmc/host/Makefile | 1 + drivers/mmc/host/stm32-sdmmc.c | 708 +++++++++++++++++++++ drivers/mmc/host/stm32-sdmmc.h | 220 +++++++ 9 files changed, 1038 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/mmc/st,stm32-sdmmc.txt create mode 100644 drivers/mmc/host/stm32-sdmmc.c create mode 100644 drivers/mmc/host/stm32-sdmmc.h -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
