I've been working on the PXA DMA transition for some days now, and
tweaked the mmp-pdma driver in order to make it work in pure DT
environments.
I also ported over most PXA peripheral drivers, but that will take some
more time to settle. I'll post those in a separate series. Up front,
here are some patches for the mmp-pdma that can be reviewed and merged
independently.
With these patches applied, I can successfully use pxa3xx-nand, pxamci
and audio on a custom pxa3xx board.
I'm including two patches from Xiang Wang which have been posted
but not yet merged, as far as I can tell.
Many thanks,
Daniel
