Patch 'dmaengine: edma: Add dummy driver skeleton for edma3-tptc' alone is
fixing the issue:
https://lkml.org/lkml/2015/11/2/297

I have tested it on: OMAP-L138-EVM, am335x-evmsk, am437x-gp-evm, dra7-evm (I
have local patches to enable and use eDMA).
All looks fine, mmc/audio works and they use eDMA.

Olof: can you run a quick test with the linked patch?

Thank you,
Péter
