fsl_dma_private: p-substream DMA data
Each substream has a 1-to-1 association with a DMA channel.
The link[] array is first because it needs to be aligned on a 32-byte boundary, so putting it first will ensure alignment without padding the structure.
]: array of link descriptors : pointer to the DMA channel's registers : IRQ for this DMA channel : pointer to the substream object, needed by the ISR : bus address of the STX or SRX register to use : physical address of the LD buffer : index into link[] of the link currently being processed : physical address of the DMA buffer : physical address of the next period to process : physical address of the byte after the end of the DMA period_size: the size of a single period : the number of periods in the DMA buffer
