Changes since v1: - ASoC patches removed - Comments from Andriy Shevchenko addressed - patch added to fix cases when src/dst_maxburst is set to 0 Adding support for DMA pause/resume Possibility to select non default event queue/TC for cyclic (audio) dma channels: all devices using the eDMA via dmaengine was assigned to the default EQ/TC (mmc, i2c, spi, etc, and audio). This is not optimal from system performance point of view since sharing the same EQ/TC can cause latency spikes for cyclic channels (long DMA transfers for MMC for example). While debugging the edma to get things sorted out I noticed that the debug was too verbose and the important information was hidden even when the we did not asked for verbose dmaengine debug. I have included some debug cleanups for the edma dmaengine driver also.
