#1720131 — [PATCH v4 0/4] Add STM32 MDMA driver

This patchset adds support for the STM32 MDMA controller.
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:
     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
