Hi Lars,

I left it somewhat ambiguous as to what this series claims to support,
sorry about that. This series, by itself, supports only platforms using
SDMA (omap 2/3/4/5 assuming you add the appropriate DMA dts bits). This
is only part of what am33xx requires for working mmc support. I've also
posted v3 of dmaengine slave sg caps series at
https://lkml.org/lkml/2013/2/4/561

I have to rebase the am33xx specific bits for omap_hsmmc on top of that
and post. That was previously all contained in one series but I didn't
want to block omap2/3/4/5 from working DMA on DT support until the api
change is resolved for am33xx.

-Matt
