thermal: Remove core header inclusion from drivers

2023-02-15T16:29:48+00:00

As the name states "thermal_core.h" is the header file for the core
components of the thermal framework.

Too many drivers are including it. Hopefully the recent cleanups
helped to self encapsulate the code a bit more and prevented the
drivers to need this header.

Remove this inclusion in every place where it is possible.

Some other drivers did a confusion with the core header and the one
exported in linux/thermal.h. They include the former instead of the
latter. The changes also fix this.

The tegra/soctherm driver still remains as it uses an internal
function which need to be replaced.

The Intel HFI driver uses the netlink internal framework core and
should be changed to prevent to deal with the internals.

No functional changes intended.

thermal/drivers/bcm2835: Use devm_platform_get_and_ioremap_resource()

2023-01-18T21:14:11+00:00

Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.

thermal/drivers/broadcom: 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/broadcom: 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/bcm2711: Don't clamp temperature at zero

2022-05-19T10:11:51+00:00

The thermal sensor on BCM2711 is capable of negative temperatures, so don't
clamp the measurements at zero. Since this was the only use for variable t,
drop it.

This change based on a patch by Dom Cobley, who also tested the fix.
