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

Browse Source 
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.

This driver add support for the INT33FE ACPI device found on
some Intel Cherry Trail devices.
There are two kinds of INT33FE ACPI device possible: for hardware
with USB Type-C and Micro-B connectors. This driver supports both.
The INT33FE ACPI device has a CRS table with I2cSerialBusV2
resources for 3 devices: Maxim MAX17047 Fuel Gauge Controller,
resources for Fuel Gauge Controller and (in the Type-C variant)
FUSB302 USB Type-C Controller and PI3USB30532 USB switch.
This driver instantiates i2c-clients for these, so that standard
i2c drivers for these chips can bind to the them.
If you enable this driver it is advised to also select
CONFIG_TYPEC_FUSB302=m and CONFIG_BATTERY_MAX17042=m.
