thermal/drivers/tegra/soctherm-fuse: Prepare calibration for Tegra114 support

2025-09-25T20:11:00+00:00

The Tegra114 has a different fuse calibration register layout and address compared to other Tegra SoCs, requiring SOCTHERM shift, mask, register address, and nominal tf calibration value to be configurable.

thermal: Use dev_fwnode()

2025-07-15T13:33:02+00:00

irq_domain_create_simple() takes fwnode as the first argument. It can be extracted from the struct device using dev_fwnode() helper instead of using of_node with of_fwnode_handle(). So use the dev_fwnode() helper. Signed-off-by: Jiri Slaby (SUSE) Cc: Amit Kucheria Cc: Thara Gopinath Cc: Rafael J.

thermal: Switch to irq_domain_create_linear()

2025-05-16T19:06:11+00:00

irq_domain_add_linear() is going away as being obsolete now. Switch to the preferred irq_domain_create_linear(). That differs in the first parameter: It takes more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

thermal: Switch back to struct platform_driver::remove()

2024-11-13T15:17:57+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/thermal to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. On the way make a few whitespace changes to make indention consistent.

thermal: tegra: Use thermal_zone_for_each_trip() for walking trip points

2024-08-02T11:50:04+00:00

It is generally inefficient to iterate over trip indices and call thermal_zone_get_trip() every time to get the struct thermal_trip corresponding to the given trip index, so modify the Tegra thermal drivers to use thermal_zone_for_each_trip() for walking trips.

thermal: tegra: Introduce struct trip_temps for critical and hot trips

2024-08-02T11:48:03+00:00

Introduce a helper structure, struct trip_temps, for storing the temperatures of the critical and hot trip points. This helps to make the code in tegra_tsensor_get_hw_channel_trips() somewhat cleaner and will be useful subsequently in eliminating iteration over trip indices from the driver. No intentional functional impact. Signed-off-by: Rafael J. Wysocki Reviewed-by: Lukasz Luba Link: https://patch.msgid.link/9333090.CDJkKcVGEf@rjwysocki.net

thermal: trip: Pass trip pointer to .set_trip_temp() thermal zone callback

2024-07-12T13:14:01+00:00

Out of several drivers implementing the .set_trip_temp() thermal zone operation, three don't actually use the trip ID argument passed to it, two call __thermal_zone_get_trip() to get a struct thermal_trip corresponding to the given trip ID, and the other use the trip ID as an index into their own data structures with the assumption that it will always match the ordering of entries in the trips table passed to the core during thermal zone registration, which is fragile and not really guaranteed. Even though the trip IDs used by the core are in fact their indices in the trips table passed to it by the thermal zone creator, that is purely a matter of convenience and should not be relied on for correctness. For this reason, modify trip_point_temp_store() to pass a (const) trip pointer to .set_trip_temp() and adjust the drivers implementing it accordingly. This helps to simplify the drivers invoking __thermal_zone_get_trip() from their .set_trip_temp() callback functions because they will not need to do it now and the other drivers can store their internal trip indices in the priv field in struct thermal_trip and their .set_trip_temp() callback functions can get those indices from there. The intel_quark_dts thermal driver can instead use the trip type to determine the requisite trip index. Signed-off-by: Rafael J.

thermal: tegra-bpmp: Convert to platform remove callback returning void

2023-10-02T12:24:13+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 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. Signed-off-by: Uwe Kleine-König Acked-by: Daniel Lezcano Signed-off-by: Rafael J. Wysocki
