Merge tag 'omap-for-v3.15/dt-part3' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt
Pull "omap device tree changes for v3.15, part 3" from Tony Lindgren:
Device tree related changes to the omap iommu driver as that
is finally getting updated. Also few trivial board related
.dts updates to add more devices.
