Well, you suggested not using of_dma_simple_xlate() since it wasn't
appropriate. I then started to implement an open-coded xlate function,
but found that it was 99% identical to the same thing in the mmp driver,
and hence created a common of_dma_slave_xlate() so as not to just
cut/paste it everywhere. Unfortunately, I only sent that patch to
dmaengine at vger.kernel.org and the DMA maintainers, and there's no
archive of that list:-(
