Subject[RESEND PATCH 0/2] STM32 DMA alternative REQ/ACK protocol support
Date
Default REQ/ACK protocol consists in maintaining ACK signal up to the
removal of REQuest and the transfer completion.
In case of alternative REQ/ACK protocol, ACK de-assertion does not wait the
removal of the REQuest, but only the transfer completion.
Due to a possible DMA stream lock when transferring data to/from STM32
USART/UART, add support to select alternative REQ/ACK protocol.

Amelie Delaunay (2):
dt-bindings: dma: add alternative REQ/ACK protocol selection in
stm32-dma
dmaengine: stm32-dma: add alternate REQ/ACK protocol management
