Guenter Roeck ddaefa209c hwmon: Make chip parameter for with_info API mandatory
Various attempts were made recently to "convert" the old
hwmon_device_register() API to devm_hwmon_device_register_with_info()
by just changing the function name without actually converting the
driver. Prevent this from happening by making the 'chip' parameter of
devm_hwmon_device_register_with_info() mandatory.

Michael Walle c8f55be4a1 hwmon: add driver for the Microchip LAN966x SoC
Add support for the temperatur sensor and the fan controller on the
Microchip LAN966x SoC. Apparently, an Analog Bits PVT sensor is used
which can measure temperature and process voltages. But only a forumlae
for the temperature sensor is known. Additionally, the SoC support a fan
tacho input as well as a PWM signal to control the fan.

The temperature register is a 16-bit, read-only register.
The MSB (Bit 15) is a leading zero and never set. Bits 14
to 5 are the 1+9 temperature data bits in a two's
complement format. Bits 4 to 0 are useless copies of
Bit 5 value and therefore ignored.

This was tested on a Aerohive HiveAP-350.

Bonus: lm70 supports TMP122/TMP124 as well.

Aleksandr Mezin 53e68c20ae hwmon: add driver for NZXT RGB&Fan Controller/Smart Device v2.
This driver implements monitoring and control of fans plugged into the
device. Besides typical speed monitoring and PWM duty cycle control,
voltage and current are reported for every fan.

The device also has 2 connectors for RGB LEDs, support for them isn't
implemented (mainly because there is no standardized sysfs interface).

Also, the device has a noise sensor, but the sensor seems to be completely
useless (and very imprecise), so support for it isn't implemented too.

The driver coexists with userspace tools that access the device through
hidraw interface with no known issues.

The driver has been tested on x86_64, built in and as a module.

Some changes/improvements were suggested by Jonas Malaco.

Denis Pauk b87611d437 hwmon: (asus_wmi_ec_sensors) Support B550 Asus WMI.
Linux HWMON sensors driver for ASUS motherboards to read
sensors from the embedded controller.

Many ASUS motherboards do not publish all the available
sensors via the Super I/O chip but the missing ones are
available through the embedded controller (EC) registers.

This driver implements reading those sensor data via the
WMI method BREC, which is known to be present in all ASUS
motherboards based on the AMD 500 series chipsets (and
probably is available in other models too). The driver
needs to know exact register addresses for the sensors and
thus support for each motherboard has to be added explicitly.

The EC registers do not provide critical values for the
sensors and as such they are not published to the HWMON.

Supported motherboards:
* PRIME X570-PRO
* Pro WS X570-ACE
* ROG CROSSHAIR VIII HERO
* ROG CROSSHAIR VIII DARK HERO
* ROG CROSSHAIR VIII FORMULA
* ROG STRIX X570-E GAMING

Guenter Roeck 38d9f06c57 hwmon: (tmp401) Drop support for TMP461
TMP461 is almost identical to TMP451, which is already supported by the
lm90 driver. At the same time, unlike other sensors from the TMP401
compatible series, it only supports 8-bit temperature read operations,
and it supports negative temperatures when configured for its default
temperature range, and it supports a temperature offset register.
Supporting this chip in the tmp401 driver adds unnecessary complexity.
Remove its support from this driver and support the chip with the lm90
driver instead.

Guenter Roeck f8344f7693 hwmon: (lm90) Add basic support for TI TMP461
TMP461 is almost identical to TMP451 and was actually detected as TMP451
with the existing lm90 driver if its I2C address is 0x4c. Add support
for it to the lm90 driver. At the same time, improve the chip detection
function to at least try to distinguish between TMP451 and TMP461.

As a side effect, this fixes commit 24333ac26d ("hwmon: (tmp401) use
smb word operations instead of 2 smb byte operations"). TMP461 does not
support word operations on temperature registers, which causes bad
temperature readings with the tmp401 driver. The lm90 driver does not
perform word operations on temperature registers and thus does not have
this problem.

Support is listed as basic because TMP461 supports a sensor resolution
of 0.0625 degrees C, while the lm90 driver assumes a resolution of 0.125
degrees C. Also, the TMP461 supports negative temperatures with its
default temperature range, which is not the case for similar chips
supported by the lm90 and the tmp401 drivers. Those limitations will be
addressed with follow-up patches.

Aleksa Savic 0e35f63f7f hwmon: add driver for Aquacomputer D5 Next
This driver exposes hardware sensors of the Aquacomputer D5 Next
watercooling pump, which communicates through a proprietary USB HID
protocol.

Available sensors are pump and fan speed, power, voltage and current, as
well as coolant temperature. Also available through debugfs are the serial
number, firmware version and power-on count.

Attaching a fan is optional and allows it to be controlled using
temperature curves directly from the pump. If it's not connected,
the fan-related sensors will report zeroes.

The pump can be configured either through software or via its physical
interface. Configuring the pump through this driver is not implemented,
as it seems to require sending it a complete configuration. That
includes addressable RGB LEDs, for which there is no standard sysfs
interface. Thus, that task is better suited for userspace tools.

This driver has been tested on x86_64, both in-kernel and as a module.
