Merge tag 'omap-for-v3.15/dt-overo-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt
Updates to the .dts files to support more Gumstix boards.
These are sent separately from the rest of the .dts changes
as these depend on the fixes merged into v3.14-rc4, and
needed a bit more time to get updated on the fixes.
