Commit 1cd1ecb6 ("thermal: exynos: Remove non DT based support")
cleaned up some non-DT code. However, there were few more things
needed for complete cleanup to make this driver DT only.Signed-off-by: Sachin Kamat

TMU probe function now checks for a device tree defined regulator.
For compatibility reasons it is allowed to probe driver even without
this regulator defined.Acked-by: Jonghwa Lee

This patch adds support for h/w mode calibration in the TMU controller.
Soc's like 5440 support this features. The h/w bits needed for calibration
setting are same as that of enum calibration_type.Acked-by: Jonghwa Lee

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.Acked-by: Jonghwa Lee

This patch adds several features supported by TMU as bitfields.
This features varies across different SOC type and comparing

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.Acked-by: Kukjin Kim

This patch adds entries min_efuse_value, max_efuse_value, default_temp_offset,
trigger_type, cal_type, trim_first_point, trim_second_point, max_trigger_level
trigger_enable in the TMU platform data structure. Also the driver is modified
to use the data passed by these new platform memebers instead of the constant
macros. All these changes helps in separating the SOC specific data part from
the TMU driver.Acked-by: Kukjin Kim

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.Acked-by: Kukjin Kim
