    The node should be named "dma-controller", not "edma",according to ePAPR 
section 2.2.2:

So you mean something like the following?

edma: dma-controller@49000000 {
  ...
}


Thanks,

Hi Sebastian,

Is this patch different from that one:
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg92176.html

Lokesh just pointed me this patch because it was missing for the 
SHAM/AES series from Mark Greer.

Bottom-line, I've just applied the original one along with a second one 
that was adding EDMA in SPI.

Regards,
Benoit

Sebastian just submitted another version of the patch [1]. This is the latest
version of the EDMA DT patch. If its ok, could you use this patch? You could
ignore all earlier versions.
