[PATCH 4/5] dmaengine: dw: Ignore burst setting for memory peripherals

2020-07-30 Thread Serge Semin
According to the DW DMA controller Databook (page 40 "3.5 Memory Peripherals") memory peripherals don't have handshaking interface connected to the controller, therefore they can never be a flow controller. Since the CTLx.SRC_MSIZE and CTLx.DEST_MSIZE are properties valid only for peripherals with
