thermal: Switch back to struct platform_driver::remove()

2024-11-13T15:17:57+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/thermal to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

On the way make a few whitespace changes to make indention consistent.

move asm/unaligned.h to linux/unaligned.h

asm/unaligned.h is always an include of asm-generic/unaligned.h;

thermal: qcom: Use thermal_zone_get_crit_temp() in qpnp_tm_init()

2024-08-02T11:46:10+00:00

Modify qpnp_tm_init() to use thermal_zone_get_crit_temp() to get the
critical trip temperature instead of iterating over trip indices and
using thermal_zone_get_trip() to get a struct thermal_trip pointer
from a trip index until it finds the critical one.

Merge branch 'thermal-core'

2024-07-15T18:43:21+00:00

Merge updates related to the thermal core for 6.11-rc1:

 - Redesign the .set_trip_temp() thermal zone callback to take a trip
   pointer instead of a trip ID and update its users (Rafael Wysocki).

 - Avoid using invalid combinations of polling_delay and passive_delay
   thermal zone parameters (Rafael Wysocki).

 - Update a cooling device registration function to take a const
   argument (Krzysztof Kozlowski).

 - Make the uniphier thermal driver use thermal_zone_for_each_trip() for
   walking trip points (Rafael Wysocki).

* thermal-core:
  thermal: core: Add sanity checks for polling_delay and passive_delay
  thermal: trip: Fold __thermal_zone_get_trip() into its caller
  thermal: trip: Pass trip pointer to .set_trip_temp() thermal zone callback
  thermal: imx: Drop critical trip check from imx_set_trip_temp()
  thermal: trip: Add conversion macros for thermal trip priv field
  thermal: helpers: Introduce thermal_trip_is_bound_to_cdev()
  thermal: core: Change passive_delay and polling_delay data type
  thermal: core: constify 'type' in devm_thermal_of_cooling_device_register()

thermal: trip: Pass trip pointer to .set_trip_temp() thermal zone callback

2024-07-12T13:14:01+00:00

Out of several drivers implementing the .set_trip_temp() thermal zone
operation, three don't actually use the trip ID argument passed to it,
two call __thermal_zone_get_trip() to get a struct thermal_trip
corresponding to the given trip ID, and the other use the trip ID as an
index into their own data structures with the assumption that it will
always match the ordering of entries in the trips table passed to the
core during thermal zone registration, which is fragile and not really
guaranteed.

Even though the trip IDs used by the core are in fact their indices in the
trips table passed to it by the thermal zone creator, that is purely a
matter of convenience and should not be relied on for correctness.

For this reason, modify trip_point_temp_store() to pass a (const) trip
pointer to .set_trip_temp() and adjust the drivers implementing it
accordingly.

This helps to simplify the drivers invoking __thermal_zone_get_trip()
from their .set_trip_temp() callback functions because they will not
need to do it now and the other drivers can store their internal
trip indices in the priv field in struct thermal_trip and their
.set_trip_temp() callback functions can get those indices from there.

The intel_quark_dts thermal driver can instead use the trip type to
determine the requisite trip index.
