2013-08-15thermal: step_wise: return instance->target by defaultEduardo Valentin
In case the trend is not changing or when there is no request for throttling, it is expected that the instance would not change its requested target. This patch improves the code implementation to cover for this expected behavior. With current implementation, the instance will always reset to cdev.cur_state, even in not expected cases, like those mentioned above. This patch changes the step_wise governor implementation of get_target so that we accomplish: (a) - default value will be current instance->target, so we do not change the thermal instance target unnecessarily. (b) - the code now it is clear about what is the intention. There is a clear statement of what are the expected outcomes (c) - removal of hardcoded constants, now it is put in use the THERMAL_NO_TARGET macro. (d) - variable names are also improved so that reader can clearly understand the difference between instance cur target, next target and cdev cur_state.

2013-08-15thermal: step_wise: cdev only needs update on a new target stateShawn Guo
The cooling device only needs update on a new target state. Since we already check old target in thermal_zone_trip_update(), we can do one more check to see if it's a new target state. If not, we can reasonably save some uncecesary code execution.

2013-08-15Thermal/cpu_cooling: Return directly for the cpu out of allowed_cpus in the ↵Lan Tianyu
cpufreq_thermal_notifier() cpufreq_thermal_notifier() is to change the cpu's cpufreq in the allowed_cpus mask when associated thermal-cpufreq cdev's cooling state is changed. It's a cpufreq policy notifier handler and it will be triggered even if those cpus out of allowed_cpus has changed freq policy. cpufreq_thermal_notifier() checks the policy->cpu. If it belongs to allowed_cpus, change max_freq(default to 0) to the desire cpufreq value and pass 0 and max_freq to cpufreq_verify_within_limits() as cpufreq scope. But if not, do nothing and max_freq will remain 0. This will cause the cpufreq scope to become 0~0. This is not right. This patch is to return directly after finding cpu not belonging to allowed_cpus. Signed-off-by: Lan Tianyu <tianyu.lan@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>

2013-08-13thermal: exynos: Add support to handle many instances of TMUAmit Daniel Kachhap
This patch adds support to handle multiple instances of the TMU controllers. This is done by removing the static structure to register with the core thermal and creating it dynamically for each instance of the TMU controller. The interrupt is made shared type to handle shared interrupts. Now since the ISR needs the core thermal framework to be registered so request_irq is moved after the core registration is done. Also the identifier of the TMU controller is extracted from device tree alias. This will be used for TMU specific initialisation.

Since he is no longer interested in the work and I have rewritten a significant amount of the code, I just took the authorship over from him. It adds the imx thermal support using Temperature Monitor (TEMPMON) block found on some Freescale i.MX SoCs. The driver uses syscon regmap interface to access TEMPMON control registers and calibration data, and supports cpufreq as the cooling device.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management fixes from Rafael Wysocki: - ACPI-based memory hotplug stopped working after a recent change, because it's not possible to associate sufficiently many "physical" devices with one ACPI device object due to an artificial limit. Fix from Rafael J Wysocki removes that limit and makes memory hotplug work again. - A change made in 3.9 uncovered a bug in the ACPI processor driver preventing NUMA nodes from being put offline due to an ordering issue. Fix from Yasuaki Ishimatsu changes the ordering to make things work again. - One of the recent ACPI video commits (that hasn't been reverted so far) uncovered a bug in the code handling quirky BIOSes that caused some Asus machines to boot with backlight completely off which made it quite difficult to use them afterward. Fix from Felipe Contreras improves the quirk to cover this particular case correctly. - A cpufreq user space interface change made in 3.10 inadvertently renamed the ignore_nice_load sysfs attribute to ignore_nice which resulted in some confusion. Fix from Viresh Kumar changes the name back to ignore_nice_load. - An initialization ordering change made in 3.9 broke cpufreq on loongson2 boards. Fix from Aaro Koskinen restores the correct initialization ordering there. - Fix breakage resulting from a mistake made in 3.9 and causing the detection of some graphics adapters (that were detected correctly before) to fail. There are two objects representing the same PCIe port in the affected systems' ACPI tables and both appear as "enabled" and we are expected to guess which one to use. We used to choose the right one before by pure luck, but when we tried to address another similar corner case, the luck went away. This time we try to make our guessing a bit more educated which is reported to work on those systems. - The /proc/acpi/wakeup interface code is missing some locking which may lead to breakage if that file is written or read during hotplug of wakeup devices. That should be rare but still possible, so it's better to start using the appropriate locking there. * tag 'pm+acpi-3.11-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: Try harder to resolve _ADR collisions for bridges cpufreq: rename ignore_nice as ignore_nice_load cpufreq: loongson2: fix regression related to clock management ACPI / processor: move try_offline_node() after acpi_unmap_lsapic() ACPI: Drop physical_node_id_bitmap from struct acpi_device ACPI / PM: Walk physical_node_list under physical_node_lock ACPI / video: improve quirk check in acpi_video_bqc_quirk()
