Hi Peter,
Thank you for the patch.
While trying to port the omap_vout driver to the DMA engine API I noticed that the driver makes use of double-indexed transfers, which are not supported by the omap-dma driver. I haven't checked in details what would be required, but the interleaved API might be a good candidate for this. Do you have any plan to add support for double-indexed transfers to the omap-dma driver ?
