Merge tag 'platform-drivers-x86-v5.9-1' of git://git.infradead.org/linux-platform-drivers-x86

Pull x86 platform driver updates from Andy Shevchenko:

 - ASUS WMI driver honors BAT1 name of the battery (quite a few new
   laptops are using it)

 - Dell WMI driver supports new key codes and backlight events

 - ThinkPad ACPI driver now may use standard charge threshold interface,
   it also has been updated to provide Laptop or Desktop mode to the
   user

 - Intel Speed Select Technology gained support on Sapphire Rapids
   platform

 - Regular update of Speed Select Technology tools

 - Mellanox has been updated to support complex attributes

 - PMC core driver has been fixed to show correct names for LPM0
   register

 - HTTP links were replaced by HTTPS ones where it applies

 - Miscellaneous fixes and cleanups here and there
