488c7455d7 thermal: exynos: Add the support for Exynos5433 TMU
This patch adds the support for Exynos5433's TMU (Thermal Management Unit).
Exynos5433 has a little different register bit fields as following description:
- Support the eight trip points for rising/falling interrupt by using two registers
- Read the calibration type (1-point or 2-point) and sensor id from TRIMINFO register
- Use a little different register address

42b696e808 thermal: exynos: Fix wrong control of power down detection mode for Exynos7
This patch fixes the wrong control of PD_DET_EN (power down detection mode)
for Exynos7 because exynos7_tmu_control() always enables the power down detection
mode regardless 'on' parameter.

4531fa1684 thermal: exynos: fix: Check if data->tmu_read callback is present before read
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.

6c247393cf thermal: exynos: Add TMU support for Exynos7 SoC
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.

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.

 They are dominated by the removal of the .owner field in platform

 removing a line in a structure.
 
 Other than that, a few minor driver core and debugfs changes.  There are
 some ath9k patches coming in through this tree that have been acked by
 the wireless maintainers as they relied on the debugfs changes.

f3764e6c18 thermal: exynos: pass cpu_present_mask to cpufreq_cooling_register()
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().

0f1be51c35 thermal: cpu_cooling: check for the readiness of cpufreq layer
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.
