[ Upstream commit c3b3747d02f571da2543e719066a50dd966989d8 ]
New ASUS B650/B660/X670 boards firmware have not exposed WMI monitoring
GUID and entrypoint method WMBD could be implemented for different device
UID.
Implement the direct call to entrypoint method for monitoring the device
UID of B550/X570 boards.

[ Upstream commit 8f2fa4726faf01094d7a5be7bd0c120c565f54d9 ]
Switch the jc42 driver to use an I2C regmap to access the registers.
Also move over to regmap's built-in caching instead of adding a
custom caching implementation. This works for JC42_REG_TEMP_UPPER,
JC42_REG_TEMP_LOWER and JC42_REG_TEMP_CRITICAL as these values never
change except when explicitly written. The cache For JC42_REG_TEMP is
dropped (regmap can't cache it because it's volatile, meaning it can
change at any time) as well for simplicity and consistency with other
drivers.

Extend aquacomputer_d5next driver to expose various hardware
sensors of the Aquacomputer High Flow Next flow sensor, which
communicates through a proprietary USB HID protocol.
The High Flow Next exposes +5V voltages, water quality, conductivity
and flow readings. A temperature sensor can be connected to it, in
which case it provides its reading and an estimation of the
dissipated/absorbed power in the liquid cooling loop.
Additionally, serial number and firmware version are exposed through
debugfs.
Registry offsets were discovered and tested by users on Github [1] [2].

This driver utilises a WMI interface found in AMD 500 series ASUS boards,
to read EC registers. But it turned out that ASUS abandoned the
interface, as it disappeared from Intel 600 series boards. Additionally,
the WMI interface was incredibly slow. Therefore this driver was deprecated
in favor of the asus_ec_sensors driver, which supports more boards, more
sensors, and is faster.

NCT218 is compatible to NCT72 and NCT214. It also supports PEC (packet

Unlike NCT214 and NCT72, NCT218 does not support the undocumented secondary
chip and manufacturer ID registers at 0x3e and 0x3f and returns 0x00 when
reading those registers. The value for the chip revision register is not
documented but was observed to be 0xca. Use that information to improve

All chips supported by the ADM1021 driver are also supported by the LM90
driver. Make that support official.
After this change, the adm1021 driver is only needed if the lm90 driver
is disabled. Also, the adm1021 driver misdetects a variety of chips as
MAX1617A, which is unwanted if any of those chips is in the system.
For this reason. make the adm1021 driver dependent on !SENSORS_LM90 to
show that it is not needed if the lm90 driver is enabled, and to avoid
misdetection if a chip supported by the lm90 driver is in the system.
Devicetree nodes are not added for the added chips since it is quite
unlikely that such old chips will ever be used in a devicetree based
system. They can be added later if needed.

Both chips are quite similar to other chips of this series, so add
support for them to the lm90 driver. Also mention ON Semiconductor NCT210,
which is pin and register compatible to ADM1021A.
None of the chips support the secondary manufacturer and chip ID registers
at 0x3e and 0x3f, but return 0 when reading from those registers.
Use that information to improve the accuracy of chip detection code.

MAX1617 and LM84 are stripped-down versions of LM90, so they can easily
be supported by the LM90 driver. The most difficult part is chip detection,
since those old chips do not support manufacturer ID or chip ID registers.
The "alarms" attribute is enabled for both chips to match the functionality
of the adm1021 driver. Chip detection was improved and is less prone to
misdetection than the chip detection in the adm1021 driver.
Devicetree nodes are not added for the added chips since it is quite
unlikely that such old chips will ever be used in a devicetree based

MAX6642 is a reduced version of LM90 with no low limits and no conversion
rate register. Its alert functionality is broken, similar to many other
chips supported by the lm90 driver.

lm90 driver is disabled. Make it dependent on SENSORS_LM90=n to show that
it is not needed if the lm90 driver is enabled.

ADT7481, ADT7482, and ADT7483 are similar to ADT7461, but support two
external temperature sensors, similar to MAX6695/6696. They support an
extended temperature range similar to ADT7461. Registers for the second
external channel can be accessed directly or by using the same method as
used by MAX6695/6696. For simplicity, the access method implemented for
MAX6695/6696 is used.
The chips support PEC (packet error checking). Set the PEC feature flag
and let the user decide if it should be enabled or not (it is by default
disabled).
Even though it is only documented for ADT7483, all three chips support a
secondary manufacturer ID register at 0x3e and a chip ID register at 0x3f.
Use the contents of those registers register for improved chip detection
accuracy. Add the same check to the ADT7461A detection code since this chip
also supports the same (undocumented) registers.
Devicetree nodes are not added for the added chips since it is quite
unlikely that such old chips will ever be used in a devicetree based
system. They can be added later if needed.

This driver provides an i2c I/O mechanism for the core nct6775 driver,
as might be used by a BMC. Because the Super I/O chip is shared with
the host CPU in such a scenario (and the host should ultimately be in
control of it), the i2c driver is strictly read-only to avoid
interfering with any usage by the host (aside from the bank-select
register, which seems to be replicated for the i2c interface).

Add peci-cputemp driver for Digital Thermal Sensor (DTS) thermal
readings of the processor package and processor cores that are
accessible via the PECI interface.
The main use case for the driver (and PECI interface) is out-of-band
management, where we're able to obtain the DTS readings from an external
entity connected with PECI, e.g. BMC on server platforms.

TI's TMP464 is an I2C temperature sensor chip. This chip is similar
to TI's TMP421 chip, but with 16bit-wide registers (instead of
8bit-wide registers). The chip has one local sensor and four remote
sensors. TMP468 is similar to TMP464 but has one local and eight
remote sensors.

The TMP125 is a 2 degree Celsius accurate Digital
Temperature Sensor with a SPI interface.
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.
I added them to the Kconfig module description.

It is not the laptops, but the /proc/i8k interface that is legacy (or so
I think was the intention of the help text author). The old description
was confusing, fix this.
The phrase "Say Y if you intend to run this kernel on old Dell laptops
or want to use userspace package i8kutils." was introduced in 2015, in
commit 039ae58503f3 ("hwmon: Allow to compile dell-smm-hwmon driver without /proc/i8k")
I think that "old laptops" was about hotkey and Fn key support - this
driver in the 2.4 kernels' era apparently had these capabilities
(see: https://github.com/vitorafsr/i8kutils , description of
"repeat_rate" kernel module parameter).

In Kconfig, inside the "Processor type and features" menu, there is
the CONFIG_I8K option: "Dell i8k legacy laptop support". This is
very confusing - enabling CONFIG_I8K is not required for the kernel to
support old Dell laptops. This option is specific to the dell-smm-hwmon
driver, which mostly exports some hardware monitoring information and
allows the user to change fan speed.
This option is misplaced, so move CONFIG_I8K to drivers/hwmon/Kconfig,
where it belongs.
Also, modify the dependency order - change
select SENSORS_DELL_SMM
to
depends on SENSORS_DELL_SMM
as it is just a configuration option of dell-smm-hwmon. This includes
changing the option type from tristate to bool. It was tristate because
it could select CONFIG_SENSORS_DELL_SMM=m .
When running "make oldconfig" on configurations with
CONFIG_SENSORS_DELL_SMM enabled , this change will result in an
additional question (which could be printed several times during
bisecting). I think that tidying up the configuration is worth it,
though.
Next patch tweaks the description of CONFIG_I8K.

Using regmap lets us use the regmap subsystem for SPI vs. I2C register
accesses. It lets us hide access differences in backend code and lets
the common code just access registers without knowing their size.
We can also use regmap for register caching.

This driver provides the same data as the asus_wmi_ec_sensors driver
(and gets it from the same source) but does not use WMI, polling
the ACPI EC directly.
That provides two enhancements: sensor reading became quicker (on some
systems or kernel configuration it took almost a full second to read
all the sensors, that transfers less than 15 bytes of data), the driver
became more flexible. The driver now relies on ACPI mutex to lock access
to the EC in the same way as the WMI code does.

Using local caching in this driver had few benefits. It used cached values
for two seconds and then re-read all registers from the chip even if the
user only accessed a single attribute. On top of that, alarm attributes
were stale for up to four seconds (the first status register read reports
and clears an alarm, the second reports it cleared). Use regmap instead
for caching. Do not re-read non-volatile registers, and do not cache
volatile registers.
As part of this change, handle register read and write address differences
in regmap code. This is necessary to avoid problems with caching in the
regmap core, and ultimately simplifies the code.
Also, errors observed when reading from and writing to registers are no
longer ignored.

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.

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.

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
