11 This document describes the STM32 DMA-MDMA chaining feature. But before going
17 STM32MP1 SoCs embed both STM32 DMA and STM32 MDMA controllers. STM32 DMA
33 **STM32 MDMA**
35 STM32 MDMA (Master DMA) is mainly used to manage direct data transfers between
38 interfaces for AHB peripherals, while the STM32 MDMA acts as a second level
39 DMA with better performance. As a AXI/AHB master, STM32 MDMA can take control
46 STM32 DMA-MDMA chaining feature relies on the strengths of STM32 DMA and
47 STM32 MDMA controllers.

10 The STM32 MDMA is a general-purpose direct memory access controller capable of
12 DMA clients connected to the STM32 MDMA controller must use the format
14 a phandle to the MDMA controller plus the following five integer cells:
43 0x00: Each MDMA request triggers a buffer transfer (max 128 bytes)
44 0x1: Each MDMA request triggers a block transfer (max 64K bytes)
45 0x2: Each MDMA request triggers a repeated block transfer
46 0x3: Each MDMA request triggers a linked list transfer
