Pull x86 platform driver updates from Andy Shevchenko:
 "Here is the collected material against Platform Drivers x86 subsystem.
  It's rather bit busy cycle for PDx86, mostly due to Dell SMBIOS driver
  activity

  For this cycle we have quite an update for the Dell SMBIOS driver
  including WMI work to provide an interface for SMBIOS tokens via sysfs
  and WMI support for 2017+ Dell laptop models. SMM dispatcher code is
  split into a separate driver followed by a new WMI dispatcher. The
  latter provides a character device interface to user space.

  The git history also contains a merge of immutable branch from Wolfram
  Sang in order to apply a dependent fix to the Intel CherryTrail
  Battery Management driver.

  Other Intel drivers got a lot of cleanups. The Turbo Boost Max 3.0
  support is added for Intel Skylake.

  Peaq WMI hotkeys driver gets its own maintainer and white list of
  supported models.

  Silead DMI is expanded to support few additional platforms.

  Tablet mode via GMMS ACPI method is added to support some ThinkPad
  tablets.

  To recover from this mode, one needs to flash a valid NVM image to the
  host host controller in the same way it is done in the previous chapter.
  
 +Networking over Thunderbolt cable
 +---------------------------------
 +Thunderbolt technology allows software communication across two hosts
 +connected by a Thunderbolt cable.
 +
 +It is possible to tunnel any kind of traffic over Thunderbolt link but
 +currently we only support Apple ThunderboltIP protocol.
 +
 +If the other host is running Windows or macOS only thing you need to
 +do is to connect Thunderbolt cable between the two hosts, the
 +``thunderbolt-net`` is loaded automatically. If the other host is also
 +Linux you should load ``thunderbolt-net`` manually on one host (it does
 +not matter which one)::
 +
 +  # modprobe thunderbolt-net
 +
 +This triggers module load on the other host automatically. If the driver
 +is built-in to the kernel image, there is no need to do anything.
 +
 +The driver will create one virtual ethernet interface per Thunderbolt
 +port which are named like ``thunderbolt0`` and so on. From this point
 +you can either use standard userspace tools like ``ifconfig`` to
 +configure the interface or let your GUI to handle it automatically.
++
+ Forcing power
+ -------------
+ Many OEMs include a method that can be used to force the power of a
+ thunderbolt controller to an "On" state even if nothing is connected.
+ If supported by your machine this will be exposed by the WMI bus with
+ a sysfs attribute called "force_power".
+ 
+ For example the intel-wmi-thunderbolt driver exposes this attribute in:
+   /sys/devices/platform/PNP0C14:00/wmi_bus/wmi_bus-PNP0C14:00/86CCFD48-205E-4A77-9C48-2021CBEDE341/force_power
+ 
+   To force the power to on, write 1 to this attribute file.
+   To disable force power, write 0 to this attribute file.
+ 
+ Note: it's currently not possible to query the force power state of a platform.
