devm_hwmon_device_unregister() has no in-tree user, and its implementation
is wrong since it does not pass the to-be-removed hardware monitoring
device as parameter. I do not envision a valid use for it; drivers needing
it should not have called devm_hwmon_device_register_with_info() in the
first place. Remove it.

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.
Add OneXPlayer 2 series, OneXFly, and X1 series models. The 2/X1 series use
new registers for turbo button takeover and read fan speed. X1 has an Intel
variant so change the CPU detection at init to only check for the affected
devices. While at it, adjust formatting of some constants and reorder all
cases alphabetically for consistency. Rename OXP_OLD constants to OXP_MINI

beepers (pwm-beeper.c) and so on. Through the HWMON subsystem, the driver

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

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

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
