thermal/hwmon: Use the right device for devm_thermal_add_hwmon_sysfs()

2023-07-11T17:39:25+00:00

[ Upstream commit 4a16c190f761cb3a87dcbbf355f91c71ce1f8c0b ] 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.

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/tegra: Fix set_trip_temp() deadlock

2023-01-06T13:14:48+00:00

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.

thermal/drivers/tegra: Fix crash when getting critical temp

2023-01-06T13:14:48+00:00

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.

thermal/drivers/tegra: 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.
