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
