Merge tag 'platform-drivers-x86-v4.16-1' of git://git.infradead.org/linux-platform-drivers-x86

Pull x86 platform-driver updates from Darren Hart:
 "New model support added for Dell, Ideapad, Acer, Asus, Thinkpad, and
  GPD laptops. Improvements to the common intel-vbtn driver, including
  tablet mode, rotate, and front button support. Intel CPU support added
  for Cannonlake and platform support for Dollar Cove power button.

  Overhaul of the mellanox platform driver, creating a new
  platform/mellanox directory for the newly multi-architecture regmap
  interface.

  Significant Intel PMC update with CannonLake support, Coffeelake
  update, CPUID enumeration, module support, new read64 API, refactoring
  and cleanups.

  Revert the apple-gmux iGP IO lock, addressing reported issues with
  non-binary drivers, leaving Nvidia binary driver users to comment out
  conflicting code.

  Miscellaneous fixes and cleanups"
