Add segment granularity for BAM, as we can read the current completed segment. bdev->common.residue_granularity = DMA_RESIDUE_GRANULARITY_SEGMENT; Use DMA_SLAVE_BUSWIDTH_4_BYTES for the src/dst addr width: bdev->common.src_addr_widths = DMA_SLAVE_BUSWIDTH_4_BYTES; bdev->common.dst_addr_widths = DMA_SLAVE_BUSWIDTH_4_BYTES;
