The thermal OF code has a new API allowing to migrate the OF
initialization to a simpler approach. The ops are no longer device
tree specific and are the generic ones provided by the core code.
Convert the ops to the thermal_zone_device_ops format and use the new
API to register the thermal zone with these generic ops.

Use thermal_zone_device_{en|dis}able() and thermal_zone_device_is_enabled().
Consequently, all set_mode() implementations in drivers:
- can stop modifying tzd's "mode" member,
- shall stop taking tzd's lock, as it is taken in the helpers
- shall stop calling thermal_zone_device_update() as it is called in the
helpers
- can assume they are called when the mode truly changes, so checks to
verify that can be dropped
Not providing set_mode() by a driver no longer prevents the core from
being able to set tzd's mode, so the relevant check in mode_store() is
removed.
Other comments:
- acpi/thermal.c: tz->thermal_zone->mode will be updated only after we
return from set_mode(), so use function parameter in thermal_set_mode()
instead, no need to call acpi_thermal_check() in set_mode()
- thermal/imx_thermal.c: regmap writes and mode assignment are done in
thermal_zone_device_{en|dis}able() and set_mode() callback
- thermal/intel/intel_quark_dts_thermal.c: soc_dts_{en|dis}able() are a
part of set_mode() callback, so they don't need to modify tzd->mode, and
don't need to fall back to the opposite mode if unsuccessful, as the return
value will be propagated to thermal_zone_device_{en|dis}able() and
ultimately tzd's member will not be changed in thermal_zone_device_set_mode().
- thermal/of-thermal.c: no need to set zone->mode to DISABLED in
of_parse_thermal_zones() as a tzd is kzalloc'ed so mode is DISABLED anyway

The mutex is used to protect against writes in the configuration register.
That happens at probe time, with no possible race yet.
Then when the module is unloaded and at suspend/resume.
When the module is unloaded, it is an userspace operation, thus via a process.
Suspending the system goes through the freezer to suspend all the tasks
synchronously before continuing. So it is not possible to hit the suspend ops
in this driver while we are unloading it.
The resume is the same situation than the probe.
In other words, even if there are several places where we write the
configuration register, there is no situation where we can write it at the same
time, so far as I can judge

- Add the IRQF_ONESHOT, ack the interrupt in the threaded handler
- Remove the interrupt handler
- Set the correct value for the LAG register
- Remove all the irq_enabled stuff in the code as the interruption
handling is fixed

The DT specifies a threshold of 65000, we setup the register with a value in
the temperature resolution for the controller, 64656.
When we reach 64656, the interrupt fires, the interrupt is disabled. Then the
irq thread runs and calls thermal_zone_device_update() which will call in turn
hisi_thermal_get_temp().
The function will look if the temperature decreased, assuming it was more than
65000, but that is not the case because the current temperature is 64656
(because of the rounding when setting the threshold). This condition being
true, we re-enable the interrupt which fires immediately after exiting the irq
thread. That happens again and again until the temperature goes to more than
65000.
Potentially, there is here an interrupt storm if the temperature stabilizes at
this temperature. A very unlikely case but possible.
In any case, it does not make sense to handle dozens of alarm interrupt for
nothing.
Fix this by rounding the threshold value to the controller resolution so the
check against the threshold is consistent with the one set in the controller.

sensor could be switched but with a delay of 3-5ms. It is difficult to read
simultaneously several sensors without a big delay.
Today, just one sensor is used, it is not necessary to deal with multiple

This warning is for IRQ imbalance enabling, which is caused by
enable_irq() twice. During sensor's initialization it tries to enable
IRQ, the driver will call thermal_zone_of_sensor_register() to bind
sensors and read sensor's temperature. But at this moment the flag
"data->irq_enabled" has been not initialized as correct state, so it
finally introduces the function enabled_irq() to be called twice. In
essentially this is caused by the flag "data->irq_enabled" is
inconsistent with real hardware IRQ enabling state.
So this patch is to fix this issue, firstly init "irq_enabled" flag
before binding sensors to thermal zone. Also change to use the function
irq_get_irqchip_state() to read back real interrupt line state.

The thermal code uses int, long and unsigned long for temperatures
in different places.
Using an unsigned type limits the thermal framework to positive
temperatures without need. Also several drivers currently will report
temperatures near UINT_MAX for temperatures below 0°C. This will probably
immediately shut the machine down due to overtemperature if started below
0°C.
'long' is 64bit on several architectures. This is not needed since INT_MAX °mC
is above the melting point of all known materials.
Consistently use a plain 'int' for temperatures throughout the thermal code and
the drivers. This only changes the places in the drivers where the temperature
is passed around as pointer, when drivers internally use another type this is
not changed.
