Merge tag 'platform-drivers-x86-v5.4-1' of git://git.infradead.org/linux-platform-drivers-x86

Pull x86 platform-drivers updates from Andy Shevchenko:

 - ASUS WMI driver got a couple of updates, i.e. support of FAN is fixed
   for recent products and the charge threshold support has been added

 - Two uknown key events for Dell laptops are being ignored now to avoid
   spamming users with harmless messages

 - HP ZBook 17 G5 and ASUS Zenbook UX430UNR got accelerometer support.

 - Intel CherryTrail platforms had a regression with wake up. Now it's
   fixed

 - Intel PMC driver got fixed in order to work nicely in Xen
   environment

 - Intel Speed Select driver provides bucket vs core count relationship.
   Besides that the tools has been updated for better output

 - The PrivacyGuard is enabled on Lenovo ThinkPad laptops

 - Three tablets - Trekstor Primebook C11B 2-in-1, Irbis TW90 and Chuwi
   Surbook Mini - got touchscreen support
