I was able to start this effort independently by converting the Davinci mmc and spi drivers to dmaengine before I took this step. I've got the next micro-step of addressing omap_hsmmc in process (pending on agreement on a dmaengine api change with Vinod), cleaning up the mcasp driver is also pending this series so that it can also be converted to dmaengine. Once mcasp (or "davinci audio") is converted, we're rid of all the in-kernel users of the private API and can get rid of this...which also is helping clean up mach-davinci, of course. If I can get your ack on this patch that should move things along to these next steps.
