Merge tag 'omap-devel-dt-merged-for-v3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt
Device tree related changes for omaps.
Note that this branch is based on omap-cleanup-sparseirq-for-v3.7
to avoid merge conflicts with the sparseirq changes for gpio-twl4030
driver.
