Hi Uwe,
Tegra team is working on to enable the new dma drivr which is dmaengine 
based. We have dma legacy driver as of now in mach-tegra. Some of the 
tests are failing with new dmadriver and so we are not able to enable it.
The patch series which is posted against this is:

[PATCH 0/5] ARM: tegra: move all APB DMA client to dmaengine based driver

Thanks,
Laxman
