This patch series fix the support of dw-edma HDMA NATIVE IP.
I can only test it in remote HDMA IP setup with single dma transfer, but
with these fixes it works properly.
Few fixes has also been added for eDMA version. Similarly to HDMA I have
tested only eDMA in remote setup.
Changes in v2:
- Update comments and fix typos.
- Removed patches that tackle hypothetical bug and then were not pertinent.
- Add the similar HDMA race condition in remote setup fix to eDMA IP driver.
Changes in v3:
- Fix comment style.
- Split a patch in two to differ bug fix and simple harmless typo.
