Peter Ujfalusi aa3c6ce4ea dmaengine: ti: edma: Support for polled (memcpy) completion ... When a DMA client driver does not set the DMA_PREP_INTERRUPT because it does not want to use interrupts for DMA completion or because it can not rely on DMA interrupts due to executing the memcpy when interrupts are disabled it will poll the status of the transfer. Since we can not tell from any EDMA register that the transfer is completed, we can only know that the paRAM set has been sent to TPTC for processing we need to check the residue of the transfer, if it is 0 then the transfer is completed.
