Hi,

Changes since v1:
- dropped the patch changing the sequence of vchan_cookie_complete and
  omap_dma_start_sg in omap_dma_callback
- Use appropriate macros to find omap_chan and omap_desc in patch 6
- Use per-device pool instead of per-channel pools.

The following series with the final patch will add support for sDMA Linked List
transfer support.
Linked List is supported by sDMA in OMAP3630+ (OMAP4/5, dra7 family).
If the descriptor load feature is present we can create the descriptors for each
SG beforehand and let sDMA to walk them through.
This way the number of sDMA interrupts the kernel need to handle will drop
dramatically.
Applied all, thanks
