Kevin - What is the process or timeline for getting this patch reapplied? I am working right now on resubmitting my patch for the Davinci SPI driver, however that driver won't work as is without this patch. I could probably hack something into the SPI driver to compensate, however if all are agreed that drivers shouldn't rely on DMA events that occur before the DMA is started, then it seems better to handle the issue in the DMA driver as I did in the reverted patch.
