Merge tag 'pm-5.9-rc5' of git://
Pull power management fixes from Rafael Wysocki: "These fix three pieces of documentation and add new CPU IDs to the Intel RAPL power capping driver. Specifics: - Add CPU IDs of the TigerLake Desktop, RocketLake and AlderLake chips to the Intel RAPL power capping driver (Zhang Rui). - Add the missing energy model performance domain item to the struct device kerneldoc comment (Randy Dunlap). - Fix the struct powercap_control_type kerneldoc comment to match the actual definition of that structure and add missing item to the struct powercap_zone_ops kerneldoc comment (Amit Kucheria)" * tag 'pm-5.9-rc5' of git:// powercap: make documentation reflect code PM: <linux/device.h>: fix @em_pd kernel-doc warning powercap/intel_rapl: add support for AlderLake powercap/intel_rapl: add support for RocketLake powercap/intel_rapl: add support for TigerLake Desktop
