OK. But just reposting the patch isn't a good idea; we don't want it to
get applied directly to multiple places.

I'd included this patch in my series to add DT support into the pinctrl
subsystem, and hence I believe it was planned to merge it into that
tree. If it's needed elsewhere, I guess it should be put in a branch
that can be merged into both the pinctrl tree and elsewhere.

Linus, Grant, Rob, can you co-ordinate this? If you want, I can create
the branch and send a pull request to LinusW. I'm not sure which branch
Jean-Christophe needs this in for his IRQ work.
