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.
