Flow controller is programmable for few controllers and there are few intelligent peripherals like, Synopsys JPEG controller, that needs to be a flow controller of DMA transfers on dest side. For this, currently two drivers, pl08x and dw_dmac, support flow controller to be passed from platform to these drivers. Perhaps, this should be a part of struct dma_slave_config. This patch adds another field device_fc to this structure. User drivers must pass this as true if they want to be flow controller of certain transfers.
