I just wrote a lengthy reply to this email to explain in what ways
you got it wrong, but then I saw that Daniel has already done all
the work in the right way in August, so nevermind that.

It hasn't made it upstream yet, but see http://list-archives.org/2013/08/07/linux-mtd-lists-infradead-org/patch-00-20-arm-pxa-move-core-and-drivers-to-dmaengine/f/3444199144
for how it's done. Maybe Daniel can comment on the status of his
patches.
