2013-08-29thermal: exynos: Fix potential NULL pointer dereferenceSachin Kamat
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
This patch removes the error return in the bind/unbind routine as the platform may not register any cpufreq cooling data.

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: Add support for instance based register/unregisterAmit Daniel Kachhap
This code modifies the thermal driver to have multiple thermal zone support by replacing the global thermal zone variable with device data member of thermal_zone_device.

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.
