SubjectRe: [PATCH] dmaengine: omap-dma: Add support for memcpy
Date
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 ?
