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
