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. * tag 'platform-drivers-x86-v5.5-1' of git://git.infradead.org/linux-platform-drivers-x86: (59 commits) platform/x86: hp-wmi: Fix ACPI errors caused by passing 0 as input size platform/x86: hp-wmi: Fix ACPI errors caused by too small buffer platform/x86: intel_pmc_core: Add Comet Lake (CML) platform support to intel_pmc_core driver platform/x86: intel_pmc_core: Fix the SoC naming inconsistency platform/mellanox: Fix Kconfig indentation tools/power/x86/intel-speed-select: Display TRL buckets for just base config level tools/power/x86/intel-speed-select: Ignore missing config level platform/x86: touchscreen_dmi: Add info for the ezpad 6 m4 tablet tools/power/x86/intel-speed-select: Increment version tools/power/x86/intel-speed-select: Use core count for base-freq mask tools/power/x86/intel-speed-select: Support platform with limited Intel(R) Speed Select tools/power/x86/intel-speed-select: Use Frequency weight for CLOS tools/power/x86/intel-speed-select: Make CLOS frequency in MHz tools/power/x86/intel-speed-select: Use mailbox for CLOS_PM_QOS_CONFIG tools/power/x86/intel-speed-select: Auto mode for CLX tools/power/x86/intel-speed-select: Correct CLX-N frequency units tools/power/x86/intel-speed-select: Change display of "avx" to "avx2" tools/power/x86/intel-speed-select: Extend command set for perf-profile Add touchscreen platform data for the Schneider SCT101CTM tablet platform/x86: intel_int0002_vgpio: Pass irqchip when adding gpiochip ...
