The Master Direct memory access (MDMA) provides high-speed data transfer between memory and memory or between peripherals and memory. Contrary to STM32 DMA, the STM32 MDMA controller supports hardware LLI and uses a larger integrated FIFO (128 vs 16 bytes) --- Version history: v5: * Change 'platform_driver_probe' into 'platform_driver_register' to manage defer mechanism v4: * Add safe getter/setter macros * forbid DMA preparation in cyclic mode yet * Optimize burst and memory width for memcpy * replace of_property_xx by device_property_xx v3: * Update header template * Unsigned expression compared with zero * Rework stm32_mdma_get_max_width * moved to src/dst case where they are used in set_xfer * Change of_property_* with device_property_* * Add dev_warn whether default value is used * Indentation * Add MODULE_* v2: * change compatible into st,stm32h7-mdma to be more SoC specific * Add MDMA support in DT for H7 * Add MDMA support in STM32 defconfig --- Pierre-Yves MORDRET (4): dt-bindings: Document the STM32 MDMA bindings dmaengine: Add STM32 MDMA driver ARM: dts: stm32: Add MDMA support for STM32H743 SoC ARM: configs: stm32: Add MDMA support in STM32 defconfig .../devicetree/bindings/dma/stm32-mdma.txt | 94 ++ arch/arm/boot/dts/stm32h743.dtsi | 10 + arch/arm/configs/stm32_defconfig | 1 + drivers/dma/Kconfig | 12 + drivers/dma/Makefile | 1 + drivers/dma/stm32-mdma.c | 1666 ++++++++++++++++++++ 6 files changed, 1784 insertions(+) create mode 100644 Documentation/devicetree/bindings/dma/stm32-mdma.txt create mode 100644 drivers/dma/stm32-mdma.c -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
