Merge tag 'soc-for-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc

SoC related changes for omaps for v3.18 merge window:

- PM changes to make the code easier to use on newer SoCs
- PM changes for newer SoCs suspend and resume and wake-up events
- Minor clean-up to remove dead Kconfig options

Note that these have a dependency to the fixes-v3.18-not-urgent
tag and is based on a commit in that series.
