thermal: sysfs: Fix trip_point_hyst_store()

2023-09-18T11:13:05+00:00

After commit 2e38a2a981b2 ("thermal/core: Add a generic thermal_zone_set_trip() function") updating a trip point temperature doesn't actually work, because the value supplied by user space is subsequently overwritten with the current trip point hysteresis value. Fix this by changing the code to parse the number string supplied by user space after retrieving the current trip point data from the thermal zone. Also drop a redundant tab character from the code in question. Fixes: 2e38a2a981b2 ("thermal/core: Add a generic thermal_zone_set_trip() function") Signed-off-by: Rafael J. Wysocki Cc: 6.3+ # 6.3+

thermal: core: Fix disabled trip point check in handle_thermal_trip()

2023-09-14T19:51:49+00:00

Commit bc840ea5f9a9 ("thermal: core: Do not handle trip points with invalid temperature") added a check for invalid temperature to the disabled trip point check in handle_thermal_trip(), but that check was added at a point when the trip structure has not been initialized yet. This may cause handle_thermal_trip() to skip a valid trip point in some cases, so fix it by moving the check to a suitable place, after __thermal_zone_get_trip() has been called to populate the trip structure.

thermal: Constify the trip argument of the .get_trend() zone callback

2023-09-11T15:16:40+00:00

Add 'const' to the definition of the 'trip' argument of the .get_trend() thermal zone callback to indicate that the trip point passed to it should not be modified by it and adjust the callback functions implementing it, thermal_get_trend() in the ACPI thermal driver and __ti_thermal_get_trend(), accordingly. No intentional functional impact. Signed-off-by: Rafael J. Wysocki Reviewed-by: Michal Wilczynski

thermal/of: add missing of_node_put()

2023-09-11T15:16:36+00:00

for_each_child_of_node performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put. This was done using the Coccinelle semantic patch iterators/for_each_child.cocci Signed-off-by: Julia Lawall Signed-off-by: Rafael J. Wysocki

thermal: core: Drop thermal_zone_device_register()

2023-09-05T19:42:18+00:00

There are no more users of thermal_zone_device_register(), so drop it from the core. Note that thermal_zone_device_register_with_trips() may be renamed to thermal_zone_device_register() in the future, but only after a grace period allowing all of the possible work in progress that may be using the latter to adjust.

thermal: Use thermal_tripless_zone_device_register()

2023-09-05T19:42:18+00:00

All of the remaining callers of thermal_zone_device_register() can use thermal_tripless_zone_device_register(), so make them do so in order to allow the former to be dropped. No intentional functional impact. Signed-off-by: Rafael J. Wysocki Acked-by: Miquel Raynal

thermal: core: Add function for registering tripless thermal zones

2023-09-05T19:42:18+00:00

Multiple callers of thermal_zone_device_register() don't pass any trips to it and they might use a shortened argument list for that, so add a special function with fewer arguments for this purpose. Signed-off-by: Rafael J. Wysocki

thermal: core: Rework .get_trend() thermal zone callback

2023-08-29T18:48:35+00:00

Passing a struct thermal_trip pointer instead of a trip index to the .get_trend() thermal zone callback allows one of its 2 implementations, the thermal_get_trend() function in the ACPI thermal driver, to be simplified quite a bit, and the other implementation of it in the ti-soc-thermal driver does not even use the relevant callback argument. For this reason, change the .get_trend() thermal zone callback definition and adjust the related code accordingly. Signed-off-by: Rafael J. Wysocki

thermal: core: Drop unused .get_trip_*() callbacks

2023-08-29T18:46:31+00:00

After recent changes in the ACPI thermal driver and in the Intel DTS IOSF thermal driver, all thermal zone drivers are expected to use trip tables for initialization and none of them should implement .get_trip_type(), .get_trip_temp() or .get_trip_hyst() callbacks, so drop these callbacks entirely from the core.
