ASUS WMI driver got a big refactoring in order to support the TUF Gaming laptops. Besides that, the regression with backlight being permanently off on various EeePC laptops has been fixed. Accelerometer on HP ProBook 450 G0 shows wrong measurements due to X axis being inverted. This has been fixed. Intel PMC core driver has been extended to be ACPI enumerated if the DSDT provides device with _HID "INT33A1". This allows to convert the driver to be pure platform and support new hardware purely based on ACPI DSDT. From now on the Intel Speed Select Technology is supported thru a corresponding driver. This driver provides an access to the features of the ISST, such as Performance Profile, Core Power, Base frequency and Turbo Frequency. Mellanox platform drivers has been refactored and now extended to support more systems, including new coming ones. The OLPC XO-1.75 platform is now supported. CB4063 Beckhoff Automation board is using PMC clocks, provided via pmc_atom driver, for ethernet controllers in a way that they can't be managed by the clock driver. The quirk has been extended to cover this case. Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile the information of Chuwi Hi10 Air has been fixed to cover more models based on the same platform. Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it has been provided. It required some extension of the generic WMI library, which allows to propagate opaque context to the ->probe() of the individual drivers. This release includes debugfs clean up from Greg KH for several drivers that drop return code check and make debugfs absence or failure non-fatal. Miscellaneous fixes here and there, mostly for Acer WMI and various Intel drivers. The listed below commits are duplicated due to previously pushed fixes in v5.2 cycle: -1dd93f873d
