This patch depends on the eDMA series from Sergey (Sorry, I forgot to mention
this in cover letter):
[PATCH RESEND v5 00/24] dmaengine: dw-edma: Add RP/EP local DMA controllers support

But the eDMA series is still getting reviews and I don't hear any news about
respin. So in the next revision I'm gonna drop this patch.

Thanks,
Mani
