[PATCH v3 00/10] dma: edma: Fixes for cyclic (audio) operation

Hi,

Changes since v2:
- Dropped patch 10 from v2 (simplify direction configuration...)
- Dropped the channel priority related patches since we are going to go via
  different route for configuring the priority.
- Added ACK from Joel for the patches since they are not changed since v2

Changes since v1:
- ASoC patches removed
- Comments from Andriy Shevchenko addressed
- patch added to fix cases when src/dst_maxburst is set to 0

The series contains now only:
Support for DMA pause/resume in cyclic mode
device_slave_caps callback and DMA_CYCLIC flag correction.
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.

Regards,
Peter
