... already pushed (it must be the end of your sentence, Jean-Christophe...)

Vinod, Arnd,

- patch 1 shall be applied before any of the two others of the series
- patch 2 is pure DT modification, but relies on Jean-Christophe's
   already pushed cleanup branch in arm-soc
- patch 3 is the pure dmaengine one, but relies on the 1st patch

So, maybe the preferred way to include this material upstream is to go 
through arm-soc as suggested by Jean-Christophe.

Bye,
