Merge tag 'intc-for-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/drivers
Merge "omap intc changes for v3.18 merge window" from Tony Lindgren:
Interrupt code related clean-up for omap2 and 3 to make
it ready to move to drivers/irqchip. Note that this series
does not yet move the interrupt code to drivers, that will
be posted separately as a follow-up series.
Note that this branch has a dependency to patches both
in fixes-v3.18-not-urgent and soc-for-v3.18 and is based on
a merge. Without doing the merge, off-idle would not work
properly for git bisect.
