thermal/core: Add thermal_trip in thermal_zone

2022-07-28T15:29:56Z

The thermal trip points are properties of a thermal zone and the different sub systems should be able to save them in the thermal zone structure instead of having their own definition. Give the opportunity to the drivers to create a thermal zone with thermal trips which will be accessible directly from the thermal core framework. As we added the thermal trip points structure in the thermal zone, let's extend the thermal zone register function to have the thermal trip structures as a parameter and store it in the 'trips' field of the thermal zone structure. The thermal zone contains the trip point, we can store them directly when registering the thermal zone. That will allow another step forward to remove the duplicate thermal zone structure we find in the thermal_of code.

thermal/core: Rename 'trips' to 'num_trips'

2022-07-28T15:29:56Z

In order to use thermal trips defined in the thermal structure, rename the 'trips' field to 'num_trips' to have the 'trips' field containing the thermal trip points.

thermal/of: Move thermal_trip structure to thermal.h

2022-07-28T15:29:54Z

The structure thermal_trip is now generic and will be usable by the different sensor drivers in place of their own structure. Move its definition to thermal.h to make it accessible.

thermal/core: Remove DROP_FULL and RAISE_FULL

thermal/drivers/thermal_of: Add change_mode ops support for thermal_of sensor

2022-05-19T10:11:51Z

The sensor driver which register through thermal_of interface doesn't have an option to get thermal zone mode change notification from thermal core. Add support for change_mode ops in thermal_of interface so that sensor driver can use this ops for mode change notification.

thermal/core: Fix thermal_cooling_device_register() prototype

2021-08-14T13:40:26Z

There are two pairs of declarations for thermal_cooling_device_register() and thermal_of_cooling_device_register(), and only one set was changed in a recent patch, so the other one now causes a compile-time warning: drivers/net/wireless/mediatek/mt76/mt7915/init.c: In function 'mt7915_thermal_init': drivers/net/wireless/mediatek/mt76/mt7915/init.c:134:48: error: passing argument 1 of 'thermal_cooling_device_register' discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers] 134 | cdev = thermal_cooling_device_register(wiphy_name(wiphy), phy, | ^~~~~~~~~~~~~~~~~ In file included from drivers/net/wireless/mediatek/mt76/mt7915/init.c:7: include/linux/thermal.h:407:39: note: expected 'char *' but argument is of type 'const char *' 407 | thermal_cooling_device_register(char *type, void *devdata, | ~~~~~~^~~~ Change the dummy helper functions to have the same arguments as the normal version.

thermal/core: Remove thermal_notify_framework

2021-04-22T11:14:09Z

thermal_notify_framework just updates for a single trip point where as thermal_zone_device_update does other bookkeeping like updating the temperature of the thermal zone and setting the next trip point. The only driver that was using thermal_notify_framework was updated in the previous patch to use thermal_zone_device_update instead. Since there are no users for thermal_notify_framework remove it.

thermal/drivers/core: Use a char pointer for the cooling device name

2021-03-15T03:46:25Z

We want to have any kind of name for the cooling devices as we do no longer want to rely on auto-numbering. Let's replace the cooling device's fixed array by a char pointer to be allocated dynamically when registering the cooling device, so we don't limit the length of the name. Rework the error path at the same time as we have to rollback the allocations in case of error. Tested with a dummy device having the name: "Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch" A village on the island of Anglesey (Wales), known to have the longest name in Europe.

thermal/core: Make cooling device state change private

2021-01-19T21:31:10Z

The change of the cooling device state should be used by the governor or at least by the core code, not by the drivers themselves. Remove the API usage and move the function declaration to the internal headers.
