The following series are various fixes and improvements for supporting suspend-to-ram. This depends on the following for basic functionality: series 1/6 where powerdomain fixes were involved. This will at least allow wake up from an internal source such as from a wakeup timer: For example with https://github.com/nmenon/linux-2.6-playground/commit/92e5e7407aa707ad6be8ae3b5bf21cfc741daab6 pinctrl series allows for external wakeup event sources like pushbutton etc. NOTE: OMAP5 and DRA7 definitions of power states and suspend targets are almost identical (except for core power domain target state as part of suspend). NOTE: This also needs missing hwmod and dts entries for various peripherals that will eventually arrive over a period of time. This is part 5/6 series which actually enables framework for suspend-to-ram and cpuidle for OMAP5 and DRA7 Each of series is based on v3.17-rc1 and this specific series is available: weblink: https://github.com/nmenon/linux-2.6-playground/commits/push/v3.17/powerdomain-fixes git repo: https://github.com/nmenon/linux-2.6-playground.git push/v3.17/powerdomain-fixes An complete integrated branch is available here: https://github.com/nmenon/linux-2.6-playground/commits/testing/v3.17/cpu-idle-suspend-dra7-omap5-framework Example test log: DRA7 based BeagleBoard X15: http://slexy.org/view/s2jgsH8bos (wakeup from external using pinctrl wakeup).
