Sia Jee Heng 8e55444da6 dmaengine: dw-axi-dmac: Support burst residue granularity ... Add support for DMA_RESIDUE_GRANULARITY_BURST so that AxiDMA can report DMA residue. Existing AxiDMA driver only support data transfer between memory to memory operation, therefore reporting DMA residue to the DMA clients is not supported. Reporting DMA residue to the DMA clients is important as DMA clients shall invoke dmaengine_tx_status() to understand the number of bytes been transferred so that the buffer pointer can be updated accordingly.
