2014-11-21thermal: Exynos: Deletion of unnecessary checks before two function callsMarkus Elfring
The functions cpufreq_cooling_unregister() and thermal_zone_device_unregister() test whether their argument is NULL and then return immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
2014-01-02thermal:samsung: fix compilation warningNaveen Krishna Chatradhi
This patch fixes a compilation warning. warning: passing argument 5 of 'thermal_zone_device_register' discards 'const' qualifier from pointer target type [enabled by default] include/linux/thermal.h:270:29: note: expected 'struct thermal_zone_device_ops *' but argument is of type 'const struct thermal_zone_device_ops *' Signed-off-by: Naveen Krishna Chatradhi <ch.naveen@samsung.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
2013-10-15thermal: exynos: Remove check for thermal device pointer at ↵Lukasz Majewski
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.

NULL pointer was being dereferenced in its own error message. Changed it to the correct device pointer. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Eduardo Valentin <eduardo.valentin@ti.com>
2013-08-13thermal: exynos: use device resource management infrastructureAmit Daniel Kachhap
This patch uses the device pointer stored in the configuration structure and converts to dev_* prints and devm API's.

2013-08-13thermal: exynos: Make the zone handling use trip informationAmit Daniel Kachhap
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.

2013-08-13thermal: exynos: Return success even if no cooling data suppliedAmit Daniel Kachhap

2013-08-13thermal: exynos: Modify private_data to appropriate name driver_dataAmit Daniel Kachhap
This patch renames member private_data to driver_data of the thermal zone registration structure as this item stores the driver related data and uses it to call the driver related callbacks.

2013-08-13thermal: exynos: Move exynos_thermal.h from include/* to driver/* folderAmit Daniel Kachhap
This patch renames and moves include/linux/platform_data/exynos_thermal.h to drivers/thermal/samsung/exynos_tmu.h. This file movement is needed as exynos SOC's are not supporting non-DT based platforms and this file now just contains exynos tmu driver related definations. Also struct freq_clip_table is now moved to exynos_thermal_common.c as it fixes the compilation issue occuring because now this new tmu header file is included in tmu driver c file and not in the common thermal header file.

2013-08-13thermal: exynos: Bifurcate exynos thermal common and tmu controller codeAmit Daniel Kachhap
This code bifurcates exynos thermal implementation into common and sensor specific parts. The common thermal code interacts with core thermal layer and core cpufreq cooling parts and is independent of SOC specific driver. This change is needed to cleanly add support for new TMU sensors.
