Pull x86 platform driver updates from Hans de Goede:
 "Highlights:

  New drivers:
   - asus-tf103c-dock
   - intel_crystal_cove_charger
   - lenovo-yogabook-wmi
   - simatic-ipc platform-code + led driver + watchdog driver
   - x86-android-tablets (kernel module to workaround DSDT bugs on
     these)

  amd-pmc:
   - bug-fixes
   - smar trace buffer support

  asus-wmi:
   - support for custom fan curves

  int3472 (camera info ACPI object for Intel IPU3/SkyCam cameras):
   - ACPI core + int3472 changes to delay enumeration of camera sensor
     I2C clients until the PMIC for the sensor has been fully probed
   - Add support for board data (DSDT info is incomplete) for setting up
     the tps68470 PMIC used on some boards with these cameras
   - Add board data for the Microsoft Surface Go (original, v2 and v3)

  thinkpad_acpi:
   - various cleanups
   - support for forced battery discharging (for battery calibration)
   - support to inhibit battery charging
   - this includes power_supply core changes to add new APIs for this

  think_lmi:
   - enhanced BIOS password support

  various other small fixes and hardware-id additions"
