Merge tag 'platform-drivers-x86-v5.8-1' of git://git.infradead.org/linux-platform-drivers-x86 

Pull x86 platform driver updates from Andy Shevchenko:

 - Add a support of the media keys on the ASUS laptop UX325JA/UX425JA

 - ASUS WMI driver can now handle 2-in-1 models T100TA, T100CHI, T100HA,
   T200TA

 - Big refactoring of Intel SCU driver with Elkhart Lake support has
   been added

 - Slim Bootloarder firmware update signaling WMI driver has been added

 - Thinkpad ACPI driver can handle dual fan configuration on new P and X
   models

 - Touchscreen DMI driver has been extended to support
    - MP-man MPWIN895CL tablet
    - ONDA V891 v5 tablet
    - techBite Arc 11.6
    - Trekstor Twin 10.1
    - Trekstor Yourbook C11B

These files allow sending arbitrary IPC commands to the PMC/SCU which
may be dangerous. These will be removed eventually and should not be
used in any new applications.
What: /sys/bus/platform/devices/INT34D2:00/simplecmd
Date: Jun 2015
KernelVersion: 4.1
Contact: Mika Westerberg <mika.westerberg@linux.intel.com>
Description: This interface allows userspace to send an arbitrary
IPC command to the PMC/SCU.
Format: %d %d where first number is command and
second number is subcommand.
What: /sys/bus/platform/devices/INT34D2:00/northpeak
Date: Jun 2015
KernelVersion: 4.1
Contact: Mika Westerberg <mika.westerberg@linux.intel.com>
Description: This interface allows userspace to enable and disable
Northpeak through the PMC/SCU.
Format: %u.

What: /sys/bus/wmi/devices/44FADEB1-B204-40F2-8581-394BBDC1B651/firmware_update_request
Date: April 2020
KernelVersion: 5.7
Contact: "Jithu Joseph" <jithu.joseph@intel.com>
Description:
Allow user space entities to trigger update of Slim
Bootloader (SBL). This attribute normally has a value
of 0 and userspace can signal SBL to update firmware,
on next reboot, by writing a value of 1.
There are two available states:
* 0 -> Skip firmware update while rebooting
* 1 -> Attempt firmware update on next reboot
