thermal: Explicitly include correct DT includes

2023-07-31T18:03:42+00:00

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.

thermal/drivers/stm32: Convert to platform remove callback returning void

2023-06-26T10:03:14+00:00

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 (mostly) ignored 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. st_thermal_unregister() always returned zero, so convert it to return void without any loss and then just drop the return from st_mmap_remove().

thermal/drivers/stm: Don't set no_hwmon to false

2023-04-01T18:51:45+00:00

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.

thermal: Remove debug or error messages in get_temp() ops

2023-03-03T19:45:02+00:00

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.

thermal/core: Use the thermal zone 'devdata' accessor in thermal located drivers

2023-03-03T19:45:02+00:00

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.

thermal/drivers/st: Remove syscfg based driver

2023-02-15T16:30:04+00:00

The syscfg based thermal driver is only supporting STiH415 STiH416 and STiD127 platforms which are all no more supported. We can thus safely remove this driver since the remaining STi platform STiH407/STiH410 and STiH418 are all using the memmap based thermal driver.

thermal: Remove core header inclusion from drivers

2023-02-15T16:29:48+00:00

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.

thermal/drivers/st: Switch to new of API

2022-08-17T12:09:38+00:00

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.
