Up till now Exynos5250 and Exynos4412 had the same definitions for TMU
data. Following commit changes that, by introducing separate
exynos4412_default_tmu_data structure.
Since Exynos4412 was chronologically first, the corresponding name for
TMU registers and default data was renamed.
Additionally, new SOC_ARCH_EXYNOS4412 type has been defined.
Moreover, the SOC_ARCH_EXYNOS name has been changed to SOC_ARCH_EXYNOS5250.

The commit 4de0bdaa96
("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.

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.

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.

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 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.

trigger_type, cal_type, trim_first_point, trim_second_point, max_trigger_level

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.
