Merge tag 'thermal-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull thermal control updates from Rafael Wysocki:
 "These add support for Intel Panther Lake processors in multiple
  places, modify Intel thermal drivers to stop selecting the user space
  thermal governor which is not necessary for them to work any more and
  clean up the thermal core somewhat:

   - Add support for Panther Lake processors in multiple places (Zhang
     Rui, Srinivas Pandruvada)

   - Remove explicit user_space governor selection from Intel thermal
     drivers (Srinivas Pandruvada)

   - Rename a few things and relocate a comment in the thermal subsystem
     (Rafael Wysocki)"

* tag 'thermal-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  thermal: core: Rename function argument related to trip crossing
  thermal: gov_bang_bang: Relocate regulation logic description
  thermal: core: Rename callback functions in two governors
  thermal: intel: Fix compile issue when CONFIG_NET is not defined
  thermal: intel: int340x: Panther Lake power floor and workload hint support
  thermal: intel: int340x: Panther Lake DLVR support
  thermal: intel: Remove explicit user_space governor selection
  ACPI: DPTF: Support Panther Lake
  thermal: intel: int340x: processor: Enable MMIO RAPL for Panther Lake
