The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

This function call was found to be unnecessary as there is no equivalent
platform_get_drvdata() call to access the private data of the driver. Also,
the private data is defined in this driver, so there is no risk of it being

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The driver is using the devm_thermal_of_zone_device_register().
In the error path of the function calling
devm_thermal_of_zone_device_register(), the function
devm_thermal_of_zone_unregister() should be called instead of
thermal_of_zone_unregister(), otherwise this one will be called twice
when the device is freed.
The same happens for the remove function where the devm_ guarantee the
thermal_of_zone_unregister() will be called, so adding this call in
the remove function will lead to a double free also.
Use devm_ variant in the error path of the probe function.
Remove thermal_of_zone_unregister() in the remove function.

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.

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 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.
Use the devdata accessor introduced in the previous patch.
No functional changes intended.

As the name states "thermal_core.h" is the header file for the core
components of the thermal framework.
Too many drivers are including it. Hopefully the recent cleanups
helped to self encapsulate the code a bit more and prevented the
drivers to need this header.
Remove this inclusion in every place where it is possible.
Some other drivers did a confusion with the core header and the one
exported in linux/thermal.h. They include the former instead of the
latter. The changes also fix this.
The tegra/soctherm driver still remains as it uses an internal
function which need to be replaced.
The Intel HFI driver uses the netlink internal framework core and
should be changed to prevent to deal with the internals.
No functional changes intended.

At the time the brcmstb_thermal driver and its binding were merged, the
DT binding did not make the coefficients properties a mandatory one,
therefore all users of the brcmstb_thermal driver out there have a non
functional implementation with zero coefficients. Even if these
properties were provided, the formula used for computation is incorrect.
The coefficients are entirely process specific (right now, only 28nm is
supported) and not board or SoC specific, it is therefore appropriate to
hard code them in the driver given the compatibility string we are
probed with which has to be updated whenever a new process is
introduced.
We remove the existing coefficients definition since subsequent patches
are going to add support for a new process and will introduce new
coefficients as well.

Stingray SoC has six temperature sensor and those are
configured, controlled and accessed to read temperature
and update in DDR memory using m0 firmware.
All six sensors has been given 4 bytes of memory in DDR
to write temperature in millivolts.
This thermal driver read temperature values from DDR
because no direct access to sensors.
Like this all temparature sensors are monitored and
trips at critical temperature.
If driver can't handle thermal runaways because of
any unknown reason, then firmware in m0 Processor
will handle.

Using devm_thermal_zone_of_sensor_register allows to simplify some
error handling code, drop a label, and drop the remove function.

By defaul of-based thermal driver do not enable hwmon.
This patch does this explicitly, so that the temperature can be read
through the common hwmon sysfs.

The thermal_zone_of_device_ops structure can be const as it is only
passed as the last argument of thermal_zone_of_sensor_register
and the corresponding parameter is declared as const.
Done with the help of Coccinelle.

Printk format "%pCr" will be removed soon, as clk_get_rate() must not be
called in atomic context.
Replace it by printing the variable that already holds the clock rate.
Note that calling clk_get_rate() is safe here, as the code runs in task
context.

The AVS TMON core provides temperature readings, a pair of configurable
high- and low-temperature threshold interrupts, and an emergency
over-temperature chip reset. The driver utilizes the first two to
provide temperature readings and high-temperature notifications to
applications. The over-temperature reset is not exposed to
applications; this reset threshold is critical to the system and should
be set with care within the bootloader.
Applications may choose to utilize the notification mechanism, the
temperature reading mechanism (e.g., through polling), or both.

The thermal_zone_of_device_ops structure is only passed as the fourth
argument to thermal_zone_of_sensor_register, which is declared as const.
Thus the thermal_zone_of_device_ops structure itself can be const.

This causes a static checker because we're passing a valid pointer to
PTR_ERR(). "err" is already the correct error code, so we can just
delete this line.

Northstar is a SoC family commonly used in home routers. This commit
adds a driver for checking CPU temperature. As Northstar Plus seems to
also have this IP block this new symbol gets ARCH_BCM_IPROC dependency.
