Messages in this thread Patch in this message | | | From | Daniel Lezcano <> | Subject | [PATCH v2] thermal/drivers/intel: Use generic trip points for quark_dts | Date | Wed, 1 Feb 2023 23:36:16 +0100 |
| |
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.

This patch applies on top of linux-pm/linux-next
V2: - Changed get_trip_temp() to return THERMAL_TEMP_INVALID - Register unconditonnaly the thermal trips - Fixed thermal_zone_device_register() call replaced by the _with_trips() version
