thermal: rename notify_thermal_framework to thermal_notify_framework

2013-04-24T16:56:16+00:00

To follow the prefix names used by the thermal functions,
this patch renames notify_thermal_framework to thermal_notify_framework.

Thermal: build thermal governors into thermal_sys module

2013-04-14T15:28:43+00:00

The thermal governors are part of the thermal framework,
rather than a seperate feature/module.
Because the generic thermal layer can not work without
thermal governors, and it must load the thermal governors
during its initialization.

Build them into one module in this patch.

This also fix a problem that the generic thermal layer does not
work when CONFIG_THERMAL=m and CONFIG_THERMAL_GOV_XXX=y.

thermal: add a warning for temperature emulation feature

2013-04-02T13:34:42+00:00

Because this feature is for debuging purposes, it is highly
recommended to do not enable this on production systems.
This patch adds warnings for system integrators, so that
people are aware of this potential security issue.

thermal: exynos: Adapt to temperature emulation core thermal framework

2013-04-02T13:29:54+00:00

This removes the driver specific sysfs support of the temperature
emulation and uses the newly added core thermal framework for thermal
emulation. An exynos platform specific handler is added to support this.

In this patch, the exynos senor(tmu) related code and exynos framework
related (thermal zone, cooling devices) code are intentionally kept separate.
So an emulated function pointer is passed from sensor to framework. This is
beneficial in adding more sensor support using the same framework code
which is an ongoing work. The goal is to finally split them totally. Even
the existing read_temperature also follows the same execution method.

Pull thermal management updates from Zhang Rui:
 "Highlights:

   - introduction of Dove thermal sensor driver.

   - introduction of Kirkwood thermal sensor driver.

   - introduction of intel_powerclamp thermal cooling device driver.

   - add interrupt and DT support for rcar thermal driver.

thermal: sysfs: Add a new sysfs node emul_temp for thermal emulation

2013-02-06T05:45:42+00:00

This patch adds support to set the emulated temperature method in
thermal zone (sensor). After setting this feature thermal zone may
report this temperature and not the actual temperature. The emulation
implementation may be based on sensor capability through platform
specific handler or pure software emulation if no platform handler defined.

This is useful in debugging different temperature threshold and its
associated cooling action. Critical threshold's cannot be emulated.
Writing 0 on this node should disable emulation.

PM: Introduce Intel PowerClamp Driver

2013-02-06T05:45:00+00:00

Intel PowerClamp driver performs synchronized idle injection across
all online CPUs. The goal is to maintain a given package level C-state
ratio.

Compared to other throttling methods already exist in the kernel,
such as ACPI PAD (taking CPUs offline) and clock modulation, this is often
more efficient in terms of performance per watt.

Please refer to Documentation/thermal/intel_powerclamp.txt for more details.
