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

LCD Shadow control

------------------



procfs: /proc/acpi/ibm/lcdshadow



Some newer T480s and T490s ThinkPads provide a feature called

PrivacyGuard. By turning this feature on, the usable vertical and

horizontal viewing angles of the LCD can be limited (as if some privacy

screen was applied manually in front of the display).



procfs notes

^^^^^^^^^^^^



The available commands are::



	echo '0' >/proc/acpi/ibm/lcdshadow

	echo '1' >/proc/acpi/ibm/lcdshadow



The first command ensures the best viewing angle and the latter one turns

on the feature, restricting the viewing angles.





EXPERIMENTAL: UWB
