| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The thermal zone params can be used to set governor to specific thermal governor for thermal zone device. But if the thermal zone params has only governor name without thermal bind params, then the thermal zone device will not be binding to cooling device. Because tz->ops->bind operator is not invoked in bind_tz() and bind_cdev() when there is thermal zone params.

This function performs kfree(cdev) without any check. In cases where there are more device registrations other than just 'thermal_zone' and 'cooling_device' this might accidently free memory allocated them silently; and cause memory errors. This patch changes this behavior by doing kfree(cdev) only when the device pointer belongs to a real cdev i.e. cooling_device.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | x86_pkg_temp receives thermal notifications via a callback from a therm_throt driver, where thermal interrupts are processed. This callback is pkg_temp_thermal_platform_thermal_notify. Here to avoid multiple interrupts from cores in a package, we disable the source and also set a variable to avoid scheduling delayed work function. This variable is protected via spin_lock_irqsave. On one buggy platform, we still receiving interrupts even if the source is disabled. This can cause deadlock/lockdep warning, when interrupt is generated while under spinlock in work function. Change spin_lock to spin_lock_irqsave and spin_unlock to spin_unlock_irqrestore as the data it is trying to protect can also be modified in a notification call called from interrupt handler.

This field is not present on Exynos4210 and Exynos5 SoCs. However on Exynos4412 SoC it is required to set this field after reset because without it TMU shows maximal available temperature, which causes immediate platform shutdown.

* | thermal: exynos: Remove check for thermal device pointer at ↵Lukasz Majewski2013-10-151-2/+0
|/ | | | | | | | | | | | | | | | | | | | | | | exynos_report_trigger() The commit 4de0bdaa9677d11406c9becb70c60887c957e1f0 ("thermal: exynos: Add support for instance based register/unregister") broke check for presence of therm_dev at global thermal zone in exynos_report_trigger(). The resulting wrong test prevents thermal_zone_device_update() call, which calls handlers for situation when trip points are passed. Such behavior prevents thermal driver from proper reaction (when TMU interrupt is raised) in a situation when overheating is detected at TMU hardware. It turns out, that after exynos thermal subsystem redesign (at v3.12) this check is not needed, since it is not possible to register thermal zone without valid thermal device.

This patch adds a flag to make this behavior optional. Now when registering a new thermal device, the caller can optionally inform if hwmon interface is desirable. This can be done by means of passing a thermal_zone_params.no_hwmon == true. In order to keep same behavior as of today, all current calls will by default create the hwmon interface.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | thermal: exynos: Add driver support for exynos5440 TMU sensorAmit Daniel Kachhap2013-08-134-9/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch modifies TMU controller to add changes needed to work with exynos5440 platform. This sensor registers 3 instance of the tmu controller with the thermal zone and hence reports 3 temperature output. This controller supports upto five trip points. For critical threshold the driver uses the core driver thermal framework for shutdown.

| | | | | | | | | | | | | | | | | | | | | | | | This patch adds support to parse one more common set of TMU register. First set of register belongs to each instance of TMU and second set belongs to common TMU registers.

* | thermal: exynos: Add TMU features to check instead of using SOC typeAmit Daniel Kachhap2013-08-133-11/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds several features supported by TMU as bitfields. This features varies across different SOC type and comparing the features present in the TMU is more logical than comparing the soc itself.

* | thermal: exynos: Add support to handle many instances of TMUAmit Daniel Kachhap2013-08-135-118/+203
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | Recently non DT support from Exynos platform is removed and hence removing non DT support from the driver also. This will help in easy maintainence.

* | thermal: exynos: Make the zone handling use trip informationAmit Daniel Kachhap2013-08-133-28/+47
| | | | | | | | | | | | | | | | | | | | | | This code simplifies the zone handling to use the trip information passed by the TMU driver and not the hardcoded macros. This also helps in adding more zone support.
