Browse Source 
- 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).

Merge tag 'pm-5.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

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)"
