The exported thermal headers expose the thermal core structure while those
should be private to the framework. The initial idea was the thermal sensor
drivers use the thermal zone device structure pointer to pass it around from
the ops to the thermal framework API like a handler.
Unfortunately, different drivers are using and abusing the internals of this
structure to hook the associated struct device, read the internals values, take
the lock, etc ...
rn order to fix this situation, let's encapsulate the structure leaking the
more in the different drivers: the thermal_zone_device structure.
This series revisit the existing drivers using the thermal zone private
structure internals to change the access to something else. For instance, the
get_temp() ops is using the tz->dev to write a debug trace. Despite the trace
is not helpful, we can check the return value for the get_temp() ops in the
call site and show the message in this place.
With this set of changes, the thermal_zone_device is almost self-encapsulated.
As usual, the acpi driver needs a more complex changes, so that will come in a
separate series along with the structure moved the private core headers.
Changelog:
- V2:
- Collected tags
- Add mising change for ->devdata for the tsens driver
- Renamed thermal_zone_device_get_data() to thermal_zone_priv()
- Added stubs when CONFIG_THERMAL is not set
- Dropped hwmon change where we remove the tz->lock usage
Thank you all for your comments

The thermal zone device structure is exposed to the different drivers
and obviously they access the internals while that should be
restricted to the core thermal code.
In order to self-encapsulate the thermal core code, we need to prevent
the drivers accessing directly the thermal zone structure and provide
accessor functions to deal with.
Provide an accessor to the 'devdata' structure and make use of it in
the different drivers.
No functional changes intended.

The different thermal drivers are showing an error in case the
get_temp() fails. Actually no traces should be displayed in the
backend ops but in the call site of this ops.
Furthermore, the message is often a dev_dbg message where the
tz->device is used, thus using the internal of the structure from the
driver.
Show a debug message if the thermal_zone_get_temp() fails to read the
sensor temperature, so code showing the message is factored out and
the tz->device accesss is in the scope of the thermal core framework.

Some get_temp() ops implementation are showing an error or a debug
message if the reading of the sensor fails.
The debug message is already displayed from the call site of this
ops. So we can remove it.
On the other side, the error should not be displayed because in
production that can raise tons of messages.
Finally, some drivers are showing a debug message with the
temperature, this is also accessible through the trace from the core
code in the temperature_update() function.
Another benefit is the dev_* messages are accessing the thermal zone
device field from the structure, so we encapsulate even more the code
by preventing these accesses.
Remove those messages.

The thermal->tzp->no_hwmon parameter is only used when calling
thermal_zone_device_register().
Setting it to 'false' before calling thermal_add_hwmon_sysfs() has no
effect.
Remove the call and again prevent the drivers to access the thermal
internals.

The devres variant of thermal_add_hwmon_sysfs() only takes the thermal
zone structure pointer as parameter.
Actually, it uses the tz->device to add it in the devres list.
It is preferable to use the device registering the thermal zone
instead of the thermal zone device itself. That prevents the driver
accessing the thermal zone structure internals and it is from my POV
more correct regarding how devm_ is used.

Some drivers are directly using the thermal zone's 'device' structure
field.
Use the driver device pointer instead of the thermal zone device when
it is available.
Remove the traces when they are duplicate with the traces in the core
code.

The 'type' field is used as a name in the message. However we can have
multiple thermal zone with the same type. The information is not
accurate.
Moreover, the thermal zone device structure is directly accessed while
we want to improve the self-encapsulation of the code.
Replace the 'type' in the message by the thermal zone id.

The driver is reading the passive polling rate in the thermal zone
structure. We want to prevent the drivers to rummage around in the
thermal zone structure.
On the other side, the delay is what the driver passed to the
thermal_zone_device_register() function, so it has already the
information.
Reuse the information we have instead of reading the information we
set.

The thermal_hwmon is playing with the thermal core code
internals. Changing the code would be too invasive for now.
We can consider the thermal_hwmon.c is part of the thermal core code
as it provides a glue to tie the hwmon and the thermal zones.
Let's include the thermal_core.h header.
No functional change intended.

The function tegra_tsensor_enable_hw_channel() takes the thermal zone
lock to prevent "a potential" race with a call to set_trips()
callback.
The driver must not play with the thermal framework core code
internals.
The tegra_tsensor_enable_hw_channel() is called by:
- the suspend / resume callbacks
- the probe function after the thermal zones are registered
The thermal zone lock taken in this function is supposed to protect
from a call to the set_trips() callback which writes in the same
register.
The potential race is when suspend / resume are called at the same
time as set_trips. This one is called only in
thermal_zone_device_update().
- At suspend time, the 'in_suspend' is set, thus the
thermal_zone_device_update() bails out immediately and set_trips is
not called during this moment.
- At resume time, the thermal zone is updated at PM_POST_SUSPEND,
thus the driver has already set the TH2 temperature.
- At probe time, we register the thermal zone and then we set the
TH2. The only scenario I can see so far is the interrupt fires, the
thermal_zone_update() is called exactly at the moment
tegra_tsensor_enable_hw_channel() a few lines after registering it.
Disable the interrupt before setting up the hw channels and then
enable it. We close the potential race window without using the
thermal zone's lock.

The thermal zone device structure is in the process of being private
to the thermal framework core code. This driver is directly accessing
and changing the monitoring polling rate.
After discussing with the maintainers of this driver, having the
polling interval at module loading time is enough for their purpose.
Change the code to take into account the interval when the module is
loaded but restrict the permissions so the value can not be changed
afterwards.

The thermal zone parameter specifies the bang-bang governor.
The Kconfig selects the bang-bang governor. So it is pointless to test
if the governor was set for the thermal zone assuming it may not have
been compiled-in.
Remove the test and prevent another access into the thermal internals.

Haven't you introduced an accessor for tz->id in this series? Why not
use it here?
And there can be an analogous accessor for tz->type.
If there are accessors like that, they should be used consistently
everywhere as applicable IMO.

Actually it is done on purpose because the patch 9 replaces the accesses
to 'type' by 'id', the thermal_zone_device_type() accessor won't be needed.

governors are part of the thermal core code, so they are authorized to
access the thermal structure internals, that is why they are not passing
through the accessors.

Cool.
However, this is a change in behavior (albeit small) which doesn't
appear to be necessary.
What would be wrong with having a tz->type accessor too?

I'm not talking about "authorization", but about consistency.
If accessors are used consistently, it is sufficient to grep for an
accessor to find all places where the given field is accessed, for
example.

I can add the 'type' accessor but from my point of view it is not
correct because the information belongs to the thermal framework and it
is used to export the information in the sysfs which is along with the
directory name giving the id of the thermal zone.
Actually, the useful information is the id of the thermal zone, not the
type. This one can be duplicate, for instance:
cat /sys/class/thermal/thermal_zone*/type
acpitz
acpitz
Given there are few places where 'type' is used in the drivers, I prefer
to directly change that to 'id' in the next patch instead of creating
the accessor for 'type', then send another series removing it.

I'm not sure what you mean here.
Surely, the 'type' is provided by whoever registers the thermal zone,
so I'm not sure in what way it "belongs" to the framework.

That's correct, but in the particular case of DT-based systems it
comes from the DT (AFAICT) and so it allows to connect the kernel
message with the DT contents. The id could be used for that, but that
involves an extra sysfs lookup.

So you are going to change the behavior of those few places with the
only reason being aesthetics AFAICS. Is this really a good enough
reason to do that?

I meant the goal of 'type' is to be exported to sysfs, nothing else.
That is the reason why I used the word 'belongs', because it was
introduced to stay in the scope of the thermal framework, but then its
usage has been diverted to a name.
Anyway, from my POV having traces in the ops is not a good thing, so
I'll propose later to remove them and add a single message in the call
sites.
Meanwhile, I'll provide the accessor for 'type' and hopefully we do not
end up with a plethora of accessors to be used in the core code.
