Merge tag 'platform-drivers-x86-v5.2-1' of git://git.infradead.org/linux-platform-drivers-x86 

Pull x86 platform driver updates from Andy Shevchenko:
 "Gathered pile of patches for Platform Drivers x86. No surprises and no
  merge conflicts. Business as usual.

  Summary:

   - New driver of power button for Basin Cove PMIC.

   - ASUS WMI driver has got a Fn lock mode switch support.

   - Resolve a never end story with non working Wi-Fi on newer Lenovo
     Ideapad computers. Now the black list is replaced with white list.

   - New facility to debug S0ix failures on Intel Atom platforms. The
     Intel PMC and accompanying drivers are cleaned up.

   - Mellanox got a new TmFifo driver. Besides tachometer sensor and
     watchdog are enabled on Mellanox platforms.

   - The information of embedded controller is now recognized on new
     Thinkpads. Bluetooth driver on Thinkpads is blacklisted for some
     models.

   - Touchscreen DMI driver extended to support 'jumper ezpad 6 pro b'
     and Myria MY8307 2-in-1.

   - Additionally few small fixes here and there for WMI and ACPI laptop
     drivers.

   - The following is an automated git shortlog grouped by driver:

   - alienware-wmi:
      - printing the wrong error code
      - fix kfree on potentially uninitialized pointer

   - asus-wmi:
      - Add fn-lock mode switch support

   - dell-laptop:
      - fix rfkill functionality

   - dell-rbtn:
      - Add missing #include

   - ideapad-laptop:
      - Remove no_hw_rfkill_list

   - intel_pmc_core:
      - Allow to dump debug registers on S0ix failure
      - Convert to a platform_driver
      - Mark local function static

   - intel_pmc_ipc:
      - Don't map non-used optional resources
      - Apply same width for offset definitions
      - Use BIT() macro
      - adding error handling

   - intel_punit_ipc:
      - Revert "Fix resource ioremap warning"

   - mlx-platform:
      - Add mlx-wdt platform driver activation
      - Add support for tachometer speed register
      - Add TmFifo driver for Mellanox BlueField Soc

   - sony-laptop:
      - Fix unintentional fall-through

   - thinkpad_acpi:
      - cleanup for Thinkpad ACPI led
      - Mark expected switch fall-throughs
      - fix spelling mistake "capabilites" -> "capabilities"
      - Read EC information on newer models
      - Disable Bluetooth for some machines

   - touchscreen_dmi:
      - Add info for 'jumper ezpad 6 pro b' touchscreen
      - Add info for Myria MY8307 2-in-1"

* Some ideapads have a hardware rfkill switch, but most do not have one.

* There used to be a long list of DMI ids for models without a hw rfkill

* More importantly wrongly reporting the wifi radio as hw-blocked, results in

* hw-blocked results in an empty SSID list, which is a much more benign
* failure mode.
* So the default now is the much safer option of assuming there is no
