Register fans connected under EC as thermal cooling devices as well, so
these fans can then work with the thermal framework.
During the driver probing phase, we will also try to register each fan
as a thermal cooling device based on previous probe result (whether the
there are fans connected on that channel, and whether EC supports fan
control). The basic get max state, get current state, and set current
state methods are then implemented as well.

Newer EC firmware supports controlling fans through host commands, so
adding corresponding implementations for controlling these fans in the
driver for other kernel services and userspace to control them.
The driver will first probe the supported host command versions (get and
set of fan PWM values, get and set of fan control mode) to see if the
connected EC fulfills the requirements of controlling the fan, then
exposes corresponding sysfs nodes for userspace to control the fan with
corresponding read and write implementations.
As EC will automatically change the fan mode to auto when the device is
suspended, the power management hooks are added as well to keep the fan
control mode and fan PWM value consistent during suspend and resume. As
we need to access the hwmon device in the power management hook, update
the driver by storing the hwmon device in the driver data as well.

Many machines treat fan state 3 as some sort of automatic mode,
which is superior to the separate SMM calls for switching to
automatic fan mode for two reasons:
- the fan control mode can be controlled for each fan separately
- the current fan control mode can be retrieved from the BIOS
On some machines however, this special fan state does not exist.
Fan state 3 acts like a regular fan state on such machines or
does not exist at all. Such machines usually use separate SMM calls
for enabling/disabling automatic fan control.
Add support for it. If the machine supports separate SMM calls
for changing the fan control mode, then the other interface is
ignored.

Implement locking in the hardware monitoring core for drivers using
the _with_info() API functions.
Most hardware monitoring drivers need to support locking to protect
against parallel accesses from userspace. With older API functions, such
locking had to be implemented in the driver code since sysfs attributes
were created by the driver. However, the _with_info() API creates sysfs
attributes in the hardware monitoring core. This makes it easy to move
the locking primitives into that code. This has the benefit of simplifying
driver code while at the same time reducing the risk of incomplete of bad
locking implementations in hardware monitoring drivers.
While this means that all accesses are forced to be synchronized, this
has little if any practical impact since accesses are expected to be low
frequency and are typically synchronized from userspace anyway since
only a single process is accessing the data. On top of that, many drivers
use regmap, which also has its own locking scheme and already serializes
accesses.

Since the shunt voltage register and the current register now report the
same values, use the shunt voltage limit registers to report and adjust
current limits, using the same LSB as the LSB used for the actual current
register.

improve code readability.

Many chips require 64-bit variables to display the accumulated energy,
even more so since the energy units are micro-Joule. Add new sensor type
"energy64" to support reporting the chip energy as 64-bit values.
Changing the entire hardware monitoring API is not feasible, and it is only
really necessary to support reading 64-bit values for the "energyX_input"
attribute. For this reason, keep the API as-is and use type casts on both
ends to pass 64-bit pointers when reading the accumulated energy. On the
write side (which is only useful for the energyX_enable attribute), keep
passing the written value as long.

capping feature.
To enable the power capping feature of the acpi_power_meter driver on
systems other than IBM products, you must explicitly specify
the force_cap_on module parameter.
Add information to the documentation about enabling the power capping
feature with this driver, including the above, to improve user convenience.

The KEBA fan controller is found in the system FPGA of KEBA PLC devices.
It detects if the fan is removed or blocked. For fans with tacho signal
the monitoring of the speed of the fan is supported. It also supports to
regulate the speed of fans with PWM input.
The auxiliary device for this driver is instantiated by the cp500 misc
driver.

Add support for the Monolithic Power Systems MPM3695 family.
It contains four devices with suffixes: -10, -20, -25 and -100.
The device is PMBus compliant and shares characteristics with the
MPM82504.
MPM3695-25 has different VOLTAGE_SCALE_LOOP register size [11:0]
and therefore needs to have a separate compatible entry.
Tested with device tree based matching (MPM3695-10).

The EC of OneXPlayer devices used to only control the fan. This is no
longer the case, with the EC of OneXPlayer gaining additional
functionality (turbo button, turbo led, battery controls).
As it will be beneficial from a complexity perspective to retain this
driver as a single unit, move it out of hwmon, and into platform/x86.
Also, remove the hwmon documentation to prepare moving it to
Documentation/ABI/.
While at it, add myself to the maintainer's file.

devm_hwmon_device_register_with_info
A number of network PHY drivers use the following code:
name = devm_hwmon_sanitize_name(dev, dev_name(dev));
if (IS_ERR(name))
return PTR_ERR(name);
devm_hwmon_device_register_with_info(dev, name, ..);
Make this a generic fallback option and use the device name if no name
is provided to devm_hwmon_device_register_with_info(). This would allow
to simplify the affected drivers.

Add initial support for the Texas Instruments TPS25990 eFuse.
This adds the basic PMBUS telemetry support for the device.
From Karol Przybylski:
The tps25990_read_word_data function contains a block of unreachable code
caused by the syntactic structure in the PMBUS_VIRT_READ_IIN_MAX case.
Specifically, the return TPS25990_READ_IIN_PEAK; statement immediately
exits the function, making the next lines unreachable.
This patch removes the return statement, leaving the expected handling.

Writing PMBus protected registers does succeed from the smbus perspective,
even if the write is ignored by the device and a communication fault is
raised. This fault will silently be caught and cleared by pmbus irq if one
has been registered.
This means that the regulator call may return succeed although the
operation was ignored.
With this change, the operation which are not supported will be properly
flagged as such and the regulator framework won't even try to execute them.

The NCT7363Y is a fan controller which provides up to 16
independent FAN input monitors. It can report each FAN input count
values. The NCT7363Y also provides up to 16 independent PWM
outputs. Each PWM can output specific PWM signal by manual mode to
control the FAN duty outside.

Add support for manipulating the internal heater of sht4x devices.
Enabling the heater removes condensed water from the sensor surface
which disturbs the relative humidity measurements.
The heater can operate at three heating levels (20, 110 or 200
milliwatts). Also, two heating durations may be selected (0.1 or 1s).
Once the heating time elapses the heater is automatically switched off.
Changes since v3:
* struct sht4x_data: add heating_complete timestamp
* struct sht4x_data: add data_pending flag
* heater_enable_store: return -EINVAL if input != 1
* heater_enable_store: check for data->heating_complete and update it
* heater_enable_store: set data_pending flag after heating request
* sht4x_read_values: msleep if heating in progress
* sht4x_read_values: dont send measurement request if data_pending
* heater_enable attr: make it RW
* Documentation: update info about heater_enable attr
Changes since v2:
* heater_enable_store: remove unnecessary if
* Documentation: remove incorrect info about turning off the heater
* be more specific in the patch description
Changes since v1:
* explain the use case of the new attributes set
* heater_enable attr: make it write-only
* heater_enable_store: define cmd as u8 instead of u8*
* heater_enable_store: remove unreachable data path
* heater_enable_store: remove unnecessary lock
* heater_enable_store: call i2c_master_send only if status==true
* define attributes as DEVICE_ATTR_* instead of SENSOR_DEVICE_ATTR_*

INA260 is similar to other chips of the series, except it has an internal
shunt resistor. The calibration register is therefore not present. Also,
the current register address was changed, though that does not matter for
the driver since the shunt voltage register (which is now the current
register) value is already used to read the current.

While the chips supported by this driver do not directly support current
limits, they do support setting shunt voltage limits. The shunt voltage
divided by the shunt resistor value is the current. On top of that,
calibration values are set such that in the shunt voltage register and
the current register report the same values. That means we can report and
configure current limits based on shunt voltage limits, and we can do so
with much better accuracy than by setting shunt voltage limits.

Add support for the OrangePi NEO-01. It uses different registers for PWM
manual mode, set PWM, and read fan speed than previous devices. Valid PWM
input and duty cycle is 1-244, we scale this from 1-255 to maintain
compatibility with the existing interface.

handle up to 16 output ports, while the Tachometer can monitor to up to 16
input ports as well. This driver implements them by exposing two kernel
subsystems: PWM and HWMON. The PWM subsystem can be utilized alongside
existing drivers for controlling elements such as fans (pwm-fan.c),
beepers (pwm-beeper.c) and so on. Through the HWMON subsystem, the driver
provides sysfs interfaces for fan.

This driver exposes hardware sensors of the ASUS ROG RYUJIN II 360
all-in-one CPU liquid cooler, which communicates through a proprietary
USB HID protocol. Report offsets were initially discovered in [1] by
Florian Freudiger.
Available sensors are pump, internal and external
(controller) fan speed in RPM, their duties in PWM, as well as
coolant temperature.
Attaching external fans to the controller is optional and allows them
to be controlled from the device. If not connected, the fan-related
sensors will report zeroes. The controller is a separate hardware unit
that comes bundled with the AIO and connects to it to allow fan control.
The addressable LCD screen is not supported in this
driver and should be controlled through userspace tools.

This driver enables hardware monitoring support for NZXT Kraken
X53/X63/X73 and Z53/Z63/Z73 all-in-one CPU liquid coolers.
All models expose liquid temperature and pump speed (in RPM), as well as
PWM control (natively only through a temp-PWM curve, but the driver also
emulates fixed PWM control on top of that). The Z-series models
additionally expose the speed and duty of an optionally connected fan,
with the same PWM control capabilities.
Pump and fan duty control mode can be set through pwm[1-2]_enable,
where 1 is for the manual control mode and 2 is for the liquid temp
to PWM curve mode. Writing a 0 disables control of the channel through
the driver after setting its duty to 100%. As it is not possible to query
the device for the active mode, the driver keeps track of it.
The temperature of the curves relates to the fixed [20-59] C range, per
device limitations, and correlating to the detected liquid temperature.
Only PWM values (ranging from 0-255) can be set.
The addressable RGB LEDs and LCD screen, included only on Z-series models,
are not supported in this driver.

The Amphenol ChipCap 2 is a capacitive polymer humidity and temperature
sensor with an integrated EEPROM and minimum/maximum humidity alarms.
All device variants offer an I2C interface and depending on the part
number, two different output modes:
- CC2D: digital output
- CC2A: analog (PDM) output
This driver adds support for the digital variant (CC2D part numbers),
which includes the following part numbers:
- non-sleep measurement mode (CC2D23, CC2D25, CC2D33, CC2D35)
- sleep measurement mode (CC2D23S, CC2D25S, CC2D33S, CC2D35S)
The Chipcap 2 EEPROM can be accessed to configure a series of parameters
like the minimum/maximum humidity alarm threshold and hysteresis. The
EEPROM is only accessible in the command window after a power-on reset.
The default window lasts 10 ms if no Start_CM command is sent. After the
command window is finished (either after the mentioned timeout of after
a Start_NOM command is sent), the device enters the normal operation
mode and makes a first measurement automatically.
Unfortunately, the device does not provide any hardware or software
reset and therefore the driver must trigger power cycles to enter the
command mode. A dedicated, external regulator is required for that.
This driver keeps the device off until a measurement or access to the
EEPROM is required, making use of the first automatic measurement to
avoid different code paths for sleep and non-sleep devices.
The minimum and maximum humidity alarms are configured with two
registers per alarm: one stores the alarm threshold and the other one
keeps the value that turns off the alarm. The alarm signals are only
updated when a measurement is carried out.

Class-based I2C probing requires detect() and address_list both
to be set in the I2C client driver, see checks in i2c_detect().
It's misleading to declare I2C_CLASS_HWMON support if the driver
doesn't implement detect().
Class-based probing is a legacy mechanism, in addition apparently
nobody ever noticed that class-based probing has been non-functional
in both drivers from the very beginning. So drop the fragments of
class-based probing support.

This driver exposes hardware sensors of the Gigabyte AORUS Waterforce
all-in-one CPU liquid coolers, which communicate through a proprietary
USB HID protocol. Report offsets were initially discovered in [1] and
confirmed by me on a Waterforce X240 by observing the sent reports from
the official software.
Available sensors are pump and fan speed in RPM, as well as coolant
temperature. Also available through debugfs is the firmware version.
Attaching a fan is optional and allows it to be controlled from the
device. If it's not connected, the fan-related sensors will report
zeroes.
The addressable RGB LEDs and LCD screen are not supported in this
driver and should be controlled through userspace tools.

Added custom channel-specific (temp1) attribute for resolution. The wait
time for a conversion in one-shot mode (enable = 0) depends on the
resolution.
When resolution is 12-bit, the conversion time is 140ms, but the minimum
update_interval is 125ms. Handled this problem by waiting an additional
15ms (125ms + 15ms = 140ms).
Added 'mask' parameter to the shutdown_write() function. Now it can
either write or update bits, depending on the value of mask. This is
needed, because for alarms a write is necessary, but for resolution only
the resolution bits should be updated.

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).

MAX31827 is a low-power temperature switch with I2C interface.
The device is a ±1°C accuracy from -40°C to +125°C
(12 bits) local temperature switch and sensor with I2C/SM-
Bus interface. The combination of small 6-bump wafer-lev-
el package (WLP) and high accuracy makes this temper-
ature sensor/switch ideal for a wide range of applications.

Extend aquacomputer_d5next driver to expose various hardware sensors of the
Aquacomputer Leakshield leak prevention system, which communicates
through a proprietary USB HID protocol. Implemented by Noah Bergbauer [1].
Two temperature sensors are exposed, along with pressure (current, min, max
and target), reservoir volume (total and filled), pump speed and flow. Pump
speed and flow values are user provided and allow the Leakshield to
optimize its operation. Writing them to the device is subject of future
patches.

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.

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.
