Merge tag 'platform-drivers-x86-v5.5-1' of git://git.infradead.org/linux-platform-drivers-x86

Pull x86 platform driver updates from Andy Shevchenko:

 - New bootctl driver for Mellanox BlueField SoC.

 - New driver to support System76 laptops.

 - Temperature monitoring and fan control on Acer Aspire 7551 is now
   supported.

 - Previously the Huawei driver handled only hotkeys. After the
   conversion to WMI it has been expanded to support newer laptop
   models.

 - Big refactoring of intel-speed-select tools allows to use it on Intel
   CascadeLake-N systems.

 - Touchscreen support for ezpad 6 m4 and Schneider SCT101CTM tablets

 - Miscellaneous clean ups and fixes here and there.
