git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management updates from Rafael J Wysocki: - Improved system suspend/resume and runtime PM handling for the SH TMU, CMT and MTU2 clock event devices (also used by ARM/shmobile). - Generic PM domains framework extensions related to cpuidle support and domain objects lookup using names. - ARM/shmobile power management updates including improved support for the SH7372's A4S power domain containing the CPU core. - cpufreq changes related to AMD CPUs support from Matthew Garrett, Andre Przywara and Borislav Petkov. - cpu0 cpufreq driver from Shawn Guo. - cpufreq governor fixes related to the relaxing of limit from Michal Pecio. - OMAP cpufreq updates from Axel Lin and Richard Zhao. - cpuidle ladder governor fixes related to the disabling of states from Carsten Emde and me. - Runtime PM core updates related to the interactions with the system suspend core from Alan Stern and Kevin Hilman. - Wakeup sources modification allowing more helper functions to be called from interrupt context from John Stultz and additional diagnostic code from Todd Poynor. - System suspend error code path fix from Feng Hong. Fixed up conflicts in cpufreq/powernow-k8 that stemmed from the workqueue fixes conflicting fairly badly with the removal of support for hardware P-state chips. The changes were independent but somewhat intertwined. * tag 'pm-for-3.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (76 commits) Revert "PM QoS: Use spinlock in the per-device PM QoS constraints code" PM / Runtime: let rpm_resume() succeed if RPM_ACTIVE, even when disabled, v2 cpuidle: rename function name "__cpuidle_register_driver", v2 cpufreq: OMAP: Check IS_ERR() instead of NULL for omap_device_get_by_hwmod_name cpuidle: remove some empty lines PM: Prevent runtime suspend during system resume PM QoS: Use spinlock in the per-device PM QoS constraints code PM / Sleep: use resume event when call dpm_resume_early cpuidle / ACPI : move cpuidle_device field out of the acpi_processor_power structure ACPI / processor: remove pointless variable initialization ACPI / processor: remove unused function parameter cpufreq: OMAP: remove loops_per_jiffy recalculate for smp sections: fix section conflicts in drivers/cpufreq cpufreq: conservative: update frequency when limits are relaxed cpufreq / ondemand: update frequency when limits are relaxed properly __init-annotate pm_sysrq_init() cpufreq: Add a generic cpufreq-cpu0 driver PM / OPP: Initialize OPP table from device tree ARM: add cpufreq transiton notifier to adjust loops_per_jiffy for smp cpufreq: Remove support for hardware P-state chips from powernow-k8 ...
2012-09-18ARM: shmobile: use __iomem pointers for MMIOArnd Bergmann
ARM is moving to stricter checks on readl/write functions, so we need to use the correct types everywhere. This patch is a bit ugly for shmobile, which is the only platform that just uses integer literals all over the place, but I can't see a better way to do this.

2012-09-04ARM: shmobile: Rework adding devices to PM domains on MackerelRafael J. Wysocki
On SH7372 and Mackerel devices are added to PM domains through a series of rmobile_add_device_to_domain_td() calls where the last argument is always the same. This is quite inefficient, so add a common function for adding devices to PM domains that reads the domain-device pairs information from a table and use it during SH7372 and Mackerel initialization.

2012-09-04ARM: shmobile: Allow device latencies to be specified directlyRafael J. Wysocki
Make it possible to specify device start/stop and save/restore state latencies directy when adding devices to PM domains. For this purpose, introduce rmobile_add_device_to_domain_td() whose third argument is a pointer to a struct gpd_timing_data object containing device latency data. Signed-off-by: Rafael J.

2012-09-04ARM: shmobile: Make rmobile_init_pm_domain() staticRafael J. Wysocki
Since rmobile_init_pm_domain() is not called anywhere outside of arch/arm/mach-shmobile/pm-rmobile.c any more, it can be made static and its header may be removed from pm-rmobile.h. Modify the code accordingly. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Magnus Damm <damm@opensource.se>
2012-09-04ARM: shmobile: Add routine for automatic PM domains initializationRafael J. Wysocki
Add a new routine, rmobile_init_domains(), allowing the caller to initialize all generic PM objects stored in a table in one operation. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Magnus Damm <damm@opensource.se>
2012-09-04ARM: shmobile: Use domain names when adding subdomains to power domainsRafael J. Wysocki
Make the power management code under arch/arm/mach-shmobile/ use pm_genpd_add_subdomain_names() for adding subdomains to power domains, which makes it possible to drop rmobile_pm_add_subdomain() and will allow us to carry out those operations for domain objects stored in tables in a straightforward way.

2012-09-04ARM: shmobile: Use names of power domains for adding devices to themRafael J. Wysocki
Make the power management code under arch/arm/mach-shmobile/ use names of power domains instead of pointers to domain objects for adding devices to the domains. This will allow us to put the domain objects into tables and register them all in one shot going forward. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Magnus Damm <damm@opensource.se>
