Pull thermal control updates from Rafael Wysocki:
 "These mostly continue to prepare the thermal control subsystem for
  using unified representation of trip points, which includes cleanups,
  code refactoring and similar and update several drivers (for other
  reasons), which includes new hardware support.

  Specifics:

   - Add a thermal zone 'devdata' accessor and modify several drivers to
     use it (Daniel Lezcano)

   - Prevent drivers from using the 'device' internal thermal zone
     structure field directly (Daniel Lezcano)

   - Clean up the hwmon thermal driver (Daniel Lezcano)

   - Add thermal zone id accessor and thermal zone type accessor and
     prevent drivers from using thermal zone fields directly (Daniel
     Lezcano)

   - Clean up the acerhdf and tegra thermal drivers (Daniel Lezcano)

   - Add lower bound check for sysfs input to the x86_pkg_temp_thermal
     Intel thermal driver (Zhang Rui)

   - Add more thermal zone device encapsulation: prevent setting
     structure field directly, access the sensor device instead the
     thermal zone's device for trace, relocate the traces in
     drivers/thermal (Daniel Lezcano)

   - Use the generic trip point for the i.MX and remove the
     get_trip_temp ops (Daniel Lezcano)

   - Use the devm_platform_ioremap_resource() in the Hisilicon driver
     (Yang Li)

   - Remove R-Car H3 ES1.* handling as public has only access to the ES2
     version and the upstream support for the ES1 has been shutdown
     (Wolfram Sang)

   - Add a delay after initializing the bank in order to let the time to
     the hardware to initialze itself before reading the temperature
     (Amjad Ouled-Ameur)

   - Add MT8365 support (Amjad Ouled-Ameur)

   - Preparational cleanup and DT bindings for RK3588 support (Sebastian
     Reichel)

   - Add driver support for RK3588 (Finley Xiao)

   - Use devm_reset_control_array_get_exclusive() for the Rockchip
     driver (Ye Xingchen)

   - Detect power gated thermal zones and return -EAGAIN when reading
     the temperature (Mikko Perttunen)

   - Remove thermal_bind_params structure as it is unused (Zhang Rui)

   - Drop unneeded quotes in DT bindings allowing to run yamllint (Rob
     Herring)

   - Update the power allocator documentation according to the thermal
     trace relocation (Lukas Bulwahn)

   - Fix sensor 1 interrupt status bitmask for the Mediatek LVTS sensor
     (Chen-Yu Tsai)

   - Use the dev_err_probe() helper in the Amlogic driver (Ye Xingchen)

   - Add AP domain support to LVTS thermal controllers for mt8195
     (Balsam CHIHI)

   - Remove buggy call to thermal_of_zone_unregister() (Daniel Lezcano)

   - Make thermal_of_zone_[un]register() private to the thermal OF code
     (Daniel Lezcano)

   - Create a private copy of the thermal zone device parameters
     structure when registering a thermal zone (Daniel Lezcano)

   - Fix a kernel NULL pointer dereference in thermal_hwmon (Zhang Rui)

   - Revert recent message adjustment in thermal_hwmon (Rafael Wysocki)

   - Use of_property_present() for testing DT property presence in
     thermal control code (Rob Herring)

   - Clean up thermal_list_lock locking in the thermal core (Rafael
     Wysocki)

   - Add DLVR support for RFIM control in the int340x Intel thermal
     driver (Srinivas Pandruvada)"

-    This structure defines the following parameters that are used to bind
-    a zone with a cooling device for a particular trip point.
-
-    .cdev:
-	     The cooling device pointer
-    .weight:
-	     The 'influence' of a particular cooling device on this
-	     zone. This is relative to the rest of the cooling
-	     devices. For example, if all cooling devices have a
-	     weight of 1, then they all contribute the same. You can
-	     use percentages if you want, but it's not mandatory. A
-	     weight of 0 means that this cooling device doesn't
-	     contribute to the cooling of this zone unless all cooling
-	     devices have a weight of 0. If all weights are 0, then
-	     they all contribute the same.
-    .trip_mask:
-	       This is a bit mask that gives the binding relation between
-	       this thermal zone and cdev, for a particular trip point.
-	       If nth bit is set, then the cdev and thermal zone are bound
-	       for trip point n.
-    .binding_limits:
-		     This is an array of cooling state limits. Must have
-		     exactly 2 * thermal_zone.number_of_trip_points. It is an
-		     array consisting of tuples <lower-state upper-state> of
-		     state limits. Each trip will be associated with one state
-		     limit tuple when binding. A NULL pointer means
-		     <THERMAL_NO_LIMITS THERMAL_NO_LIMITS> on all trips.
-		     These limits are used when binding a cdev to a trip point.
-    .match:
