Hi Vinod, V2 of my patchset which introduces scatter-gather transfers support to the axi-dmac driver. I updated patch [1/5] with your feedback. Patch [4/5] was updated as well, so that cyclic transfers are restarted properly in the EOT. This was a bug in my V1, but it was fixed here just for bisectability, as the new patch [5/5] will improve cyclic transfers by linking the last descriptor to the first one in a SG chain, which means that the EOT IRQ only needs to call the callback associated with the cyclic transfer, and the EOT IRQ can be masked if there is no callback associated with it.
