[PATCH v2 0/4] dmaengine: xilinx: Misc (cyclic) transfers fixes

Hello,

So far all my testing was performed by looping the playback output to
the recording input and comparing the files using FFTs. Unfortunately,
when the DMA engine suffers from the same issue on both sides, some
issues may appear un-noticed. I now have proper hardware to really
listen to the actual sound, so here are a couple of fixes and
improvements.

Cheers,
Miquèl

Changes in v2:
* Added a patch to clarify the logic in the interrupt handler between
cyclic and sg transfers.
* Fixed the count of elapsed periods without breaking SG.

Miquel Raynal (4):
dmaengine: xilinx: xdma: Fix the count of elapsed periods in cyclic
mode
dmaengine: xilinx: xdma: Clarify the logic between cyclic/sg modes
dmaengine: xilinx: xdma: Better handling of the busy variable
dmaengine: xilinx: xdma: Add terminate_all/synchronize callbacks
