15 * The Spreadtrum DMA controller supports channel 2-stage tansfer, that means
16 * we can request 2 dma channels, one for source channel, and another one for
17 * destination channel. Each channel is independent, and has its own
18 * configurations. Once the source channel's transaction is done, it will
19 * trigger the destination channel's transaction automatically by hardware
22 * To support 2-stage tansfer, we must configure the channel mode and trigger
27 * enum sprd_dma_chn_mode: define the DMA channel mode for 2-stage transfer
28 * @SPRD_DMA_CHN_MODE_NONE: No channel mode setting which means channel doesn't
