I've updated the patche set based on feedback. This is tested on linux-next with LEGO MINDSTORMS EV3 (da850), both with and without device tree enabled.

The davinci_mmc driver no longer uses platform resources for getting dma
channels. Instead lookup is now done using dma_slave_map.

I can apply the patch if I get an immutable branch from Ulf post v4.6-rc1 or if Ulf decides to apply this, fine with me. Acked-by: Sekhar Nori <nsekhar@ti.com> BTW, we prefer a captialized "ARM:" in subject prefix. Whoever is applying can probably fix it though. Thanks, Sekhar

Not as reply to the original posting. With the later, there are more chances of series being lost. Thanks, Sekhar
