Sia Jee Heng eec9176053 dmaengine: dw-axi-dmac: Support device_prep_slave_sg ... Add device_prep_slave_sg() callback function so that DMA_MEM_TO_DEV and DMA_DEV_TO_MEM operations in single mode can be supported. Existing AxiDMA driver only support data transfer between memory to memory. Data transfer between device to memory and memory to device in single mode would failed if this interface is not supported by the AxiDMA driver.
