Merge tag 'platform-drivers-x86-v5.9-1' of git://git.infradead.org/linux-platform-drivers-x86

Pull x86 platform driver updates from Andy Shevchenko:

 - ASUS WMI driver honors BAT1 name of the battery (quite a few new
   laptops are using it)

 - Dell WMI driver supports new key codes and backlight events

 - ThinkPad ACPI driver now may use standard charge threshold interface,
   it also has been updated to provide Laptop or Desktop mode to the
   user

 - Intel Speed Select Technology gained support on Sapphire Rapids
   platform

 - Regular update of Speed Select Technology tools

 - Mellanox has been updated to support complex attributes

 - PMC core driver has been fixed to show correct names for LPM0
   register

 - HTTP links were replaced by HTTPS ones where it applies

 - Miscellaneous fixes and cleanups here and there

DYTC Lapmode sensor
------------------
sysfs: dytc_lapmode
Newer thinkpads and mobile workstations have the ability to determine if
the device is in deskmode or lapmode. This feature is used by user space
to decide if WWAN transmission can be increased to maximum power and is
also useful for understanding the different thermal modes available as
they differ between desk and lap mode.
The property is read-only. If the platform doesn't have support the sysfs
class is not created.

Battery charge control
----------------------
sysfs attributes:
/sys/class/power_supply/BAT*/charge_control_{start,end}_threshold
These two attributes are created for those batteries that are supported by the
driver. They enable the user to control the battery charge thresholds of the
given battery. Both values may be read and set. `charge_control_start_threshold`
accepts an integer between 0 and 99 (inclusive); this value represents a battery
percentage level, below which charging will begin. `charge_control_end_threshold`
accepts an integer between 1 and 100 (inclusive); this value represents a battery
percentage level, above which charging will stop.
The exact semantics of the attributes may be found in
Documentation/ABI/testing/sysfs-class-power.

help
Many Bay Trail and Cherry Trail devices come with a camera attached
to Intel's Image Signal Processor. Linux currently does not have a
driver for these, so they do not work as a camera. Some of these
camera's have a LED which is controlled through a GPIO.
Some of these devices have a firmware issue where the LED gets turned
on at boot. This driver will turn the LED off at boot and also allows
controlling the LED (repurposing it) through the sysfs LED interface.
Which GPIO is attached to the LED is usually not described in the
ACPI tables, so this driver contains per-system info about the GPIO
inside the driver, this means that this driver only works on systems
the driver knows about.
To compile this driver as a module, choose M here: the module
will be called intel_atomisp2_led.
