be144ee491 hwmon: (oxp-sensors) Add tt_toggle attribute on supported boards
OneXPlayer boards from the last generation (both for OneXPlayer and AOK
ZOE brands) have a toggle in the EC to switch the "Turbo/Silent" button
into a different keyboard event.

Add a means to use that "Turbo button takeover" function and expose it
to userspace in a custom sysfs `tt_toggle` attribute. It can be read to
take the current state. Write 1|0 to activate the function. The specific
keycode is dependent on the board but can be checked by running
`evtest` utility.

Newer BIOS on the OneXPlayer added this function aside from string changes.
Add a board enum to differentiate it from the old OneXplayer Mini AMD BIOS.

Currently known supported boards:
- AOK ZOE A1
- OneXPlayer Mini AMD (only newer BIOS version supported)
- OneXPlayer Mini Pro

3d2c211c0d hwmon: (sht3x) add medium repeatability support
Add support for medium repeatability.

Per datasheet:

The stated repeatability is 3 times the standard deviation (3σ)
of multiple consecutive measurements at the stated repeatability
and at constant ambient conditions. It is a measure for the noise
on the physical sensor output. Different measurement modes allow
for high/medium/low repeatability.

For the humidity sensor, repeatability is documented as
0.25% RH for low repeatability, 0.15% RH for medium repeatability,
and 0.10% RH for high repeatability. Support all three modes.

23902f98f8 hwmon: add HP WMI Sensors driver
Hewlett-Packard (and some HP Compaq) business-class computers report
hardware monitoring information via WMI. This driver exposes that
information to hwmon.

Initial support is provided for temperature, fan speed, and intrusion
sensor types. Provisional support is provided for voltage and current
sensor types.

HP's WMI implementation permits many other types of numeric sensors.
Therefore, a debugfs interface is also provided to enumerate and
inspect all numeric sensors visible on the WMI side. This should
facilitate adding support for other sensor types in the future.

Tested on a HP Z420, a HP EliteOne 800 G1, and a HP Compaq Elite 8300
SFF.

Note that provisionally supported sensor types are untested and seem
to be rare-to-nonexistent in the wild, having been encountered
neither on test systems nor in ACPI dumps from the Linux Hardware
Database. They are included because their popularity in general makes
their presence on past or future HP systems plausible and because no
doubt exists as to how the sensors themselves would be represented in
WMI (alarm attributes will need to wait for hardware to be located).
A 2005 HP whitepaper gives the relevant sensor object MOF definition
and sensor value scaling calculation, and both this driver and the
official HP Performance Advisor utility comply with them (confirmed
in the latter case by reverse engineering).

339c8f2484 hwmon: (it87) Allow for chips with only 4 temp sensors
Some chips are known to only have 4 temperature sensors and there is no
requirement to test for more.  Currently only the IT8622E fits this
category.

b153a0bb41 hwmon: (pmbus/adm1275) Fix problems with temperature monitoring on ADM1272
The PMON_CONFIG register on ADM1272 is a 16 bit register. Writing a 8 bit
value into it clears the upper 8 bits of the register, resulting in
unexpected side effects. Fix by writing the 16 bit register value.

Also, it has been reported that temperature readings are sometimes widely
inaccurate, to the point where readings may result in device shutdown due
to errant overtemperature faults. Improve by enabling temperature sampling.

While at it, move the common code for ADM1272 and ADM1278 into a separate
function, and clarify in the error message that an attempt was made to
enable both VOUT and temperature monitoring.

Last but not least, return the error code reported by the underlying I2C
controller and not -ENODEV if updating the PMON_CONFIG register fails.
After all, this does not indicate that the chip is not present, but an
error in the communication with the chip.

0babf89c9c hwmon: (f71882fg) prevent possible division by zero
In the unlikely event that something goes wrong with the device and
its registers, the fan_from_reg() function may return 0. This value
will cause a division-by-zero error in the show_pwm() function.

To prevent this, test the value of
fan_from_reg(data->fan_full_speed[nr]) against 0 before performing
the division. If the division-by-zero error is avoided, assign 0 to
the val variable.

Found by Linux Verification Center (linuxtesting.org) with static
analysis tool SVACE.
