Unfortunately, DMA_SG means something else. Maybe, we need DMA_MEMCPY_SG
to be similar with DMA_MEMSET_SG.
enum dma_transaction_type {
DMA_MEMCPY,
DMA_XOR,
DMA_PQ,
DMA_XOR_VAL,
DMA_PQ_VAL,
DMA_MEMSET,
DMA_MEMSET_SG,
DMA_INTERRUPT,
DMA_SG,
DMA_PRIVATE,
DMA_ASYNC_TX,
DMA_SLAVE,
DMA_CYCLIC,
DMA_INTERLEAVE,
/* last transaction type for creation of the capabilities mask */
DMA_TX_TYPE_END,
};
