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.
We are thinking of updating 'Documentation/devicetree/bindings/dma/dma.txt' to add the information for these extra two parameters. Is that fine or any other suggestion ? Regards, Santosh
