Subject: [PATCH 0/2] Add DMA and MDMA support on STM32MP13x SoC family

This patchset enables DMA1 and DMA2 routed on DMAMUX1, and MDMA on
STM32MP13.

Subject: [PATCH 1/2] ARM: dts: stm32: add DMA1, DMA2 and DMAMUX1 on STM32MP13x SoC family

DMA1 and DMA2 on STM32MP13x SoCs are the same than on STM32MP15x SoCs: they
offer up to 8 channels and request lines are routed through DMAMUX1.

MDMA on STM32MP13x SoCs is the same than on STM32MP15x SoCs: it offers up
to 32 channels and supports 48 requests.
