The majority of patches have had some small fixes here and there to make things work when CONFIG_PM_RUNTIME is unset. In addition to that, to make the shmobile code introduced by the last patch work for CONFIG_PM_RUNTIME unset I had to add patches [8-9/10]. Patch [7/10] adds wakeup support that was missing from the previous version and I decided not to push patch [1/10] for 3.0 after all. On Saturday, June 11, 2011, Rafael J.

[ 2/10] - Move subsys_data in struct dev_pm_info out of #ifdef CONFIG_PM_RUNTIME [ 3/10] - Introduce runtime PM support for generic I/O PM domains. [ 4/10] - Introduce generic "noirq" callbacks for system suspend/hibernation (that's necessary for the next patches). [ 5/10] - Move some PM domains support code fro under #ifdef CONFIG_PM_RUNTIME [ 6/10] - Add system-wide PM support for generic I/O PM domains. [ 7/10] - Add support for wakeup from system sleep to the I/O PM domains code. [ 8/10] - Allow PM clocks management code to be used during system suspend. [ 9/10] - Rename PM clock management functions so that they names reflect the fact that they can be used during system suspend too. [10/10] - Use the new code to represent the SH7372's A4MP power domain. All of these patches are regarded as 3.1 material and they are available from the git branch at: git://git.kernel.org/pub/scm/linux/kernel/git/rafael/suspend-2.6.git pm-domains The patchset has been tested on SH7372 Mackerel board for both CONFIG_PM_RUNTIME set and unset.
