hwmon: add driver for NZXT RGB&Fan Controller/Smart Device v2.

2021-12-26T23:02:07+00:00

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.

hwmon: (ntc_thermistor) Drop OF dependency

2021-12-26T23:02:06+00:00

The driver has been augmented to just use device properties
so the OF dependency can be dropped.

hwmon: (ntc_thermistor) Drop read_uv() depend on OF and IIO

2021-12-26T23:02:05+00:00

The only possible assignment of a function to get a voltage to
convert to a resistance is to use the internal function
ntc_adc_iio_read() which is only available when using IIO
and OF.

Bite the bullet and mandate OF and IIO, drop the read_uv()
callback abstraction and some ifdefs.

As no board is using the platform data, all users are using
OF and IIO anyway.

hwmon: (asus_wmi_ec_sensors) Support B550 Asus WMI.

2021-12-26T23:02:05+00:00

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Many ASUS motherboards do not publish all the available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
* ROG STRIX B550-I GAMING
* ROG STRIX B550-E GAMING

hwmon: (tmp401) Use regmap

2021-12-26T23:02:05+00:00

Use regmap for register accesses to be able to utilize its caching
functionality. This also lets us hide register access differences
in regmap code.

hwmon: (tmp401) Drop support for TMP461

2021-10-28T02:48:19+00:00

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.

hwmon: (lm90) Add basic support for TI TMP461

2021-10-28T02:48:19+00:00

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 24333ac26d01 ("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.

hwmon: (nct6775) Support access via Asus WMI

2021-10-12T14:22:37+00:00

Support accessing the NCT677x via Asus WMI functions.

On mainboards that support this way of accessing the chip, the driver will
usually not work without this option since in these mainboards, ACPI will
mark the I/O port as used.

Code uses ACPI firmware interface to communicate with sensors with ASUS
motherboards:
* PRIME B460-PLUS,
* ROG CROSSHAIR VIII IMPACT,
* ROG STRIX B550-E GAMING,
* ROG STRIX B550-F GAMING,
* ROG STRIX B550-F GAMING (WI-FI),
* ROG STRIX Z490-I GAMING,
* TUF GAMING B550M-PLUS,
* TUF GAMING B550M-PLUS (WI-FI),
* TUF GAMING B550-PLUS,
* TUF GAMING X570-PLUS,
* TUF GAMING X570-PRO (WI-FI).
