The thermal framework gives the possibility to register the trip
points along with the thermal zone. When that is done, no get_trip_*
callbacks are needed and they can be removed.
Convert the existing callbacks content logic into generic trip points
initialization code and register them along with the thermal zone.
In order to consolidate the code, use an ACPI trip library function
to populate a generic trip point.

The driver browses the trip point to find out the critical trip
temperature. However the function thermal_zone_get_crit_temp() does
already that, so the routine is pointless in the driver.
Use thermal_zone_get_crit_temp() instead of inspecting all the trip
points.
In addition, the hysteresis value is set to zero. A critical trip
point does not have a hysteresis.

The tsens driver reprogram the next trip points in the irq
handler. This function then call thermal_zone_device_update().
However, thermal_zone_device_update() calls thermal_zone_set_trips()
and from there it calls the backend 'set_trips' ops. This one in turn
reprogram the next trip points (low/high).
Consequently, the code setting the next trip points interrupt in the
interrupt handle is not needed and could be removed.

On msm8939 last (hwid=10) sensor was added in the hw revision 3.0.
Calibration data for it was placed outside of the main calibration data
blob, so it is not accessible by the current blob-parsing code.
Moreover data for the sensor's p2 is not contiguous in the fuses. This
makes it hard to use nvmem_cell API to parse calibration data in a
generic way.
Since the sensor doesn't seem to be actually used by the existing
hardware, disable the sensor for now.

and msm8956 SoCs. This is not quite correct, as according to the
vendor kernels, msm8976 should use standard slope values (3200), while
msm8956 really uses the slope values found in the driver.
Add separate compatibility string for msm8956, move slope value
overrides to the corresponding init function and use the standard
compute_intercept_slope() function for both platforms.

The return value from the call to intel_tcc_get_tjmax() is int, which can
be a negative error code. However, the return value is being assigned to
an u32 variable 'tj_max', so making 'tj_max' an int.
Eliminate the following warning:
./drivers/thermal/intel/intel_soc_dts_iosf.c:394:5-11: WARNING: Unsigned expression compared with zero: tj_max < 0

The thermal-zone-device lock is held by core when setting trip points
and the driver takes its chip lock in the corresponding callback.
Fetching the thermal trip points using thermal_zone_get_trip() also
involves taking the thermal-zone-device lock, which means that the chip
lock can not be held when doing so.
Drop the chip lock temporarily during probe to avoid the lock inversion
that was detected by lockdep:

The set_trip_temp() callback is used when changing the trip temperature
through sysfs. As it is called with the thermal-zone-device lock held
it must not use thermal_zone_get_trip() directly or it will deadlock.

Commit 13bea86623be ("thermal/of: Remove of_thermal_get_crit_temp()")
removed the function of_thermal_get_crit_temp() and this is causing a
NULL pointer deference crash when attempting to call the 'get_crit_temp'
function pointer because this function pointer is no longer initialised.
Fix this by replacing the call to the 'get_crit_temp' function pointer
with a call to the function thermal_zone_get_crit_temp() instead.

critical temp
The driver is assuming the get_critical temperature exists as it is
inherited by the thermal of ops. But this one has been removed in
favor of the generic one.
Use the generic thermal_zone_get_crit_temp() function instead

The thermal framework gives the possibility to register the trip
points with the thermal zone. When that is done, no get_trip_* ops are
needed and they can be removed.
Convert ops content logic into generic trip points and register them with the
thermal zone.

In the process of replacing the get_trip_* ops by the generic trip
points, the current code has an 'override' property to add another
indirection to a different ops.
Rework this approach to prevent this indirection and make the code
ready for the generic trip points conversion.
Actually the get_temp() is different regarding the platform, so it is
pointless to add a new set of ops but just create dynamically the ops
at init time.
