thermal/drivers/renesas: Group all renesas thermal drivers together

2024-07-15T11:31:38+00:00

Move all Renesas thermal drivers to a vendor specific directory. All drivers are moved verbatim apart from the updated include path for thermal_hwmon.h.

thermal: core: Eliminate writable trip points masks

2024-02-27T11:04:38+00:00

All of the thermal_zone_device_register_with_trips() callers pass zero writable trip points masks to it, so drop the mask argument from that function and update all of its callers accordingly. This also removes the artificial trip points per zone limit of 32, related to using writable trip points masks. No intentional functional impact. Signed-off-by: Rafael J.

thermal: rcar: Convert to platform remove callback returning void

2023-09-29T10:34:17+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.

thermal: Explicitly include correct DT includes

2023-07-31T18:03:42+00:00

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/hwmon: Do not set no_hwmon before calling thermal_add_hwmon_sysfs()

2023-03-03T19:45:02+00:00

The thermal->tzp->no_hwmon parameter is only used when calling thermal_zone_device_register(). Setting it to 'false' before calling thermal_add_hwmon_sysfs() has no effect. Remove the call and again prevent the drivers to access the thermal internals.

thermal/core: Use the thermal zone 'devdata' accessor in thermal located drivers

2023-03-03T19:45:02+00:00

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/rcar: Use generic thermal_zone_get_trip() function

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

The thermal framework gives the possibility to register the trip points with the thermal zone. When that is done, no get_trip_* ops are needed and they can be removed. Convert ops content logic into generic trip points and register them with the thermal zone.

thermal/drivers/rcar_thermal: Constify static thermal_zone_device_ops

2022-10-04T09:21:18+00:00

The only usage of rcar_thermal_zone_of_ops is to pass its address to devm_thermal_of_zone_register(), which takes a pointer to const struct thermal_zone_device_ops. Make it const to allow the compiler to put it in read-only memory.

thermal/drivers/rcar: 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.

thermal/drivers/rcar_thermal: Use platform_get_irq_optional() to get the interrupt

2022-05-19T10:11:50+00:00

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq_optional().
