Here is an updated v3 of the series. Series introduces support for setting up
dma parameters based on device tree properties like 'dma-ranges' and
'dma-coherent' and also update to ARM 32 bit port. Earlier version of the
series can be found here [3], [2] and [1].

Are these two generic device tree properties documented somewhere under
Documentation/devicetree/bindings?

These bindings have been already in use before this series. But looks like
they have not been documented. I will do a patch to add description for those
couple of parameters.

dma-ranges is part of ePAPR, and was documented in some ieee-1275 addenda
before that, but I agree it would be nice to have something in kernel as
well, at the minimum something pointing to the relevant documents.
