Merge branch 'thermal-intel'

Merge changes affecting thermal control on Intel platforms for 6.3-rc1:

 - Consolidate code accessing the Intel TCC (Thermal Control Circuitry)
   MSRs by introducing library functions for that and making the
   TCC-related code in thermal drivers use them (Zhang Rui).

 - Enhance the x86_pkg_temp_thermal driver to support dynamic tjmax
   changes (Zhang Rui).

 - Address an "unsigned expression compared with zero" warning in the
   intel_soc_dts_iosf thermal driver (Yang Li).

 - Update comments regarding two functions in the Intel Menlow thermal
   driver (Deming Wang).

 - Use sysfs_emit_at() instead of scnprintf() in the int340x thermal
   driver (ye xingchen).

 - Make the intel_pch thermal driver support the Wellsburg PCH (Tim
   Zimmermann).

 - Add trip point initialization helper functions for ACPI-defined trip
   points and modify two thermal drivers to use them (Rafael Wysocki,
   Daniel Lezcano).

 - Modify the intel_pch and processor_thermal_device_pci thermal drivers
   use generic trip point tables instead of thermal zone trip point
   callbacks (Daniel Lezcano).

 - Add production mode attribute sysfs attribute to the int340x thermal
   driver (Srinivas Pandruvada).

 - Rework dynamic trip point updates handling and locking in the int340x
   thermal driver (Rafael Wysocki).

 - Make the int340x thermal driver use a generic trip points table
   instead of thermal zone trip point callbacks (Rafael Wysocki, Daniel
   Lezcano).
