[PATCH v2 0/4] Add support for STM32 DMA

[M'boumba Cedric Madianga]

This patchset adds support for the STM32 DMA controller.
This controller provides 8 channels dedicated to managing memory access
request from one or more peripherals.
Each stream can have up to 8 requests in total.

Changes since v1:
- remove dmamux boolean as it is not needed
- replace dma by DMA in Kconfig
- add default return value in stm32_dma_get_width()
- add defalut return value in stm32_dma_get_burst()
- use lower case for constant hexadecimal values

M'boumba Cedric Madianga (4):
  dt-bindings: Document the STM32 DMA bindings
  dmaengine: Add STM32 DMA driver
  ARM: dts: Add STM32 DMA support for STM32F429 MCU
  ARM: configs: Add STM32 DMA support in STM32 defconfig
