The exynos_tmu_data() function should on entrance test not only for valid
data pointer, but also for data->tmu_read one.
It is important, since afterwards it is dereferenced to get temperature code.

Add registers, bit fields and compatible strings for Exynos7 TMU
(Thermal Management Unit). Following are a few of the differences
in the Exynos7 TMU from earlier SoCs:
- 8 trigger levels
- Different bit offsets and more registers for the rising
and falling thresholds.
- New power down detection bit in the TMU_CONTROL register
which does not update the CURRENT_TEMP0 when tmu power down
is detected.
- Change in bit offset for the NEXT_DATA field of EMUL_CON
register. EMUL_CON register address has also changed.
- INTSTAT and INTCLEAR registers present in earlier SoCs
have been combined into one INTPEND register. The register
address for INTCLEAR and INTPEND is also different.
- Since there are 8 rising/falling interrupts as against
at most 4 in earlier SoCs the INTEN bit offsets are different.
- Multiple probe support which is handled by a TMU_CONTROL1
register (No support for this in the current patch).
This patch adds special clock support required only for Exynos7. It
also updates the "code_to_temp" prototype as Exynos7 has 9 bit
code-temp mapping.

Up till now, by mistake, wrong variable was tested against being NULL.
Since exynos_report_trigger() is always called with valid p pointer,
it is only necessary to check if a valid thermal zone device is passed.

This patch brings support for providing configuration via device tree.

cooling configuration
Up till now exynos_tmu_data.c was used for storing CPU cooling configuration
data. Now the Exynos thermal core code uses device tree to get this data.
For this purpose generic thermal code for configuring CPU cooling was
used.

This patch is a preparatory patch to be able to read Exynos thermal
configuration from the device tree.
It turned out that DTC is not able to interpret enums properly and hence
it is necessary to #define those values explicitly.
For this reason the ./include/dt-bindings/thermal/thermal_exynos.h file
has been introduced.

As samsung thermal support is enabled only for ARCH_EXYNOS, there is no
need to select ARCH_HAS_BANDGAP from the arch-specific code. Removing this
dependency will also allow the driver to be enabled on 64-bit SoCs.

cpufreq_cooling_register() expects mask of all the CPUs where frequency
constraint is applicable.
This platform has more than one CPU to which these constraints will apply and so
passing mask of only CPU0 wouldn't be sufficient. Also, this platform has a
single cluster of CPUs and the constraint applies to all CPUs.
If CPU0 is hoplugged out then we may face strange BUGs as cpu_cooling framework
isn't aware of any siblings sharing clock line.
Fix it by passing cpu_present_mask to cpufreq_cooling_register().

In this patch, the cpu_cooling code checks for the usability of cpufreq
layer before proceeding with the CPU cooling device registration. The
main reason is: CPU cooling device is not usable if cpufreq cannot
switch frequencies.
Similar checks are spread in thermal drivers. Thus, the advantage now
is to have the check in a single place: cpu cooling device registration.
For this reason, this patch also updates the existing drivers that
depend on CPU cooling to simply propagate the error code of the cpu
cooling registration call. Therefore, in case cpufreq is not ready, the
thermal drivers will still return -EPROBE_DEFER, in an attempt to try
again when cpufreq layer gets ready.

Maximum theoretical size saving (i.e. with only Exynos5410
SoC support enabled in kernel config so all SoC dependend
Exynos thermal driver code was dropped) is 4096 bytes so
there is no much sense in keeping these ifdefs (especially
given that they are useless once the driver gets updated to
use device tree).
While at it remove needless 'void *' casts.

Exynos5250 have TMU_SUPPORT_READY_STATUS flag set in their struct
exynos_tmu_init_data instances). Please note that this requires
adding separate SoC type for Exynos5420 so it doesn't get mistaken
with Exynos5250.
This is a preparation for introducing per-SoC type tmu_initialize
method.
There should be no functional changes caused by this patch.

Replace TMU_SUPPORT_READY_STATUS flag check in
exynos_tmu_initialize() by an explicit check for a SoC type
(all SoC types except Exynos5440 have TMU_SUPPORT_READY_STATUS
flag set in their struct exynos_tmu_init_data instances).

Simplify HW_TRIP level setting in exynos_tmu_initialize() (don't
pretend that the current code is hardware and configuration
independent and just do SoC type check explicitly). Then remove
no longer needed reg->threshold_[th2,th3_l0_shift] abstractions
(only assigned for Exynos5440 in exynos5440_tmu_registers) and
EXYNOS_MAX_TRIGGER_PER_REG define.
