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
