Dst,stm32-bdma.yaml5 STM32 BDMA controller
7 The STM32 BDMA is a general-purpose direct memory access controller
8 capable of supporting 5 or 6 or 7 or 8 independent BDMA channels.
10 BDMA clients connected to the STM32 BDMA controller must use the format
12 channel: a phandle to the BDMA controller plus the following four integer cells:
13 1. channel: the bdma stream from 0 to <bdma-requests>
14 2. slot: bdma request
15 3. channel-config: A 32bit mask specifying the BDMA channel configuration
