Aleksa Savic ceaa22402e hwmon: (aquacomputer_d5next) Add support for Aquacomputer High Flow USB and MPS Flow
Extend aquacomputer_d5next driver to expose various hardware sensors of the
Aquacomputer High Flow USB flow sensor, which communicates through a
proprietary USB HID protocol. This commit also adds support for the sensors
of the MPS Flow devices, as they have the same USB product ID and sensor
layouts. Implemented by Leonard Anderweit [1].

Internal and external temp sensor readings are available, along with
the flow sensor.

Additionally, serial number and firmware version are exposed through
debugfs.

Antoniu Miclaus 2b9ea4262a hwmon: Add driver for ltc2991
Add support for LTC2991 Octal I2C Voltage, Current, and Temperature
Monitor.

The LTC2991 is used to monitor system temperatures, voltages and
currents. Through the I2C serial interface, the eight monitors can
individually measure supply voltages and can be paired for
differential measurements of current sense resistors or temperature
sensing transistors. Additional measurements include internal
temperature and internal VCC.

Missing feature:
- Accessing non-volatile memory: Custom board has no

Joaquín Ignacio Aramendía 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

James Seo 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).

through a proprietary USB HID protocol. Implemented by Leonard Anderweit
[1] [2].

Coolant temp, fan IC and external temp sensor readings are available, along
with speed and voltage of both the pump and optionally connected fan.
It also exposes pump current.

Additionally, serial number and firmware version are exposed through
debugfs.

change left a stray colon for the fan speed control method. Fix this

Leonard Anderweit bd1e92f997 hwmon: (aquacomputer_d5next) Add fan PWM control for Aquaero
Add the option to control fan PWM on Aquacomputer Aquaero. The Aquaero is
the most complex Aquacomputer device, control is therefore more complicated
then on already supported devices.
Setting PWM requires multiple steps. First, an internal static PWM
controller is set to the desired PWM value. Second, the fan is set to use
that PWM controller. Last, the minimum and maximum accepted PWM values
of the fan are set to allow all possible PWM values.

Guenter Roeck 5720a18baa hwmon: Deprecate [devm_]hwmon_device_register_with_groups
Even though the hardware monitoring documentation already stated that new
drivers should use [devm_]devm_hwmon_device_register_with_info() to
register with the hardware monitoring subsystem, we still get submissions
for new drivers using the older APIs. There is no benefit to use those
APIs. On the contrary, using the older APIs results in substantially larger
code size. Explicitly deprecate [devm_]hwmon_device_register_with_groups()
to ensure that all new drivers use the latest API.
