Add documentation for the new attributes:
- "bios_active_image"; "bios_auth_fail"; "bios_upgrade_fail";
"bios_safe_mode" to represent various BIOS statuses.
- "lc{n}_enable" - for put/release the line card to/from enable state.
- "lc{n}_pwr" - for power on/off the line card.
- "lc{n}_rst_mask" - for line card reset state enforced by ASIC, when
it sets it due to some abnormal ASIC behavior.
- "psu3_on"; "psu4_on" - for connection/disconnection power supply unit
to/from the power source.
- "pm_mgmt_en" - for setting power management control ownership. When
power management control is provided by hardware, it means that
hardware will automatically power off one or more line cards in case
system power budget is under power required for feeding all powered
on line cards. It could be a case, when some of power units lost
power good state.
- "shutdown_unlock" - for unlocking system after hardware or firmware
thermal shutdown, which causes locking of the all interfaces to ASIC.

Pull x86 platform driver updates from Andy Shevchenko:
"Gathered a bunch of x86 platform driver changes. It's rather big,
since includes two big refactors and completely new driver:
- 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.
Also miscellaneous fixes here and there, mostly for Acer WMI and
various Intel drivers"

The author of this file should be given an award for creativity:
the What: fields on this file technically fulfills the description
at README. Yet, the way it is, it can't be parsed on a script,
and if someone would try to do something like:
grep hwmon*/jtag_enable
It wouldn't find anything.
Fix the What fields in a way that it can be parseable by a
script and other search tools.
