thermal: sprd: Convert to platform remove callback returning void 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.

thermal: Explicitly include correct DT includes 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/core: Use the thermal zone 'devdata' accessor in thermal located drivers 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/sprd: Switch to new of API 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.

thermal/drivers/sprd: Add missing MODULE_DEVICE_TABLE MODULE_DEVICE_TABLE is used to extract the device information out of the driver and builds a table when being compiled. If using this macro, kernel can find the driver if available when the device is plugged in, and then loads that driver and initializes the device.

thermal: Use mode helpers in drivers Use thermal_zone_device_{en|dis}able() and thermal_zone_device_is_enabled(). Consequently, all set_mode() implementations in drivers: - can stop modifying tzd's "mode" member, - shall stop taking tzd's lock, as it is taken in the helpers - shall stop calling thermal_zone_device_update() as it is called in the helpers - can assume they are called when the mode truly changes, so checks to verify that can be dropped Not providing set_mode() by a driver no longer prevents the core from being able to set tzd's mode, so the relevant check in mode_store() is removed. Other comments: - acpi/thermal.c: tz->thermal_zone->mode will be updated only after we return from set_mode(), so use function parameter in thermal_set_mode() instead, no need to call acpi_thermal_check() in set_mode() - thermal/imx_thermal.c: regmap writes and mode assignment are done in thermal_zone_device_{en|dis}able() and set_mode() callback - thermal/intel/intel_quark_dts_thermal.c: soc_dts_{en|dis}able() are a part of set_mode() callback, so they don't need to modify tzd->mode, and don't need to fall back to the opposite mode if unsuccessful, as the return value will be propagated to thermal_zone_device_{en|dis}able() and ultimately tzd's member will not be changed in thermal_zone_device_set_mode(). - thermal/of-thermal.c: no need to set zone->mode to DISABLED in of_parse_thermal_zones() as a tzd is kzalloc'ed so mode is DISABLED anyway Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@collabora.com> [for acerhdf] Acked-by: Peter Kaestle <peter@piie.net> Reviewed-by: Amit Kucheria <amit.kucheria@linaro.org> Reviewed-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/20200629122925.21729-8-andrzej.p@collabora.com
