Subject: [PATCH v2 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:
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
