4 STM32 DMA-MDMA chaining
9 ------------
11 This document describes the STM32 DMA-MDMA chaining feature. But before going
14 To offload data transfers from the CPU, STM32 microprocessors (MPUs) embed
15 direct memory access controllers (DMA).
17 STM32MP1 SoCs embed both STM32 DMA and STM32 MDMA controllers. STM32 DMA
18 request routing capabilities are enhanced by a DMA request multiplexer
19 (STM32 DMAMUX).

10 The STM32 DMA is a general-purpose direct memory access controller capable of
11 supporting 8 independent DMA channels. Each channel can have up to 8 requests.
12 DMA clients connected to the STM32 DMA controller must use the format
13 described in the dma.txt file, using a four-cell specifier for each
14 channel: a phandle to the DMA controller plus the following four integer cells:
